| 1 | PM_(2.5) and PM_(10-2.5) chemical composition and source apportionment near a Hong Kong roadway显示文摘Twenty-four-hour PM_(2.5) and PM_(10) samples were collected simultaneously at a highly trafficked roadside site in Hong Kong every sixth day from October 2004 to September 2005.The mass concentrations of PM_(2.5),PM_(10-2.5)(defined as PM_(10)- PM_(2.5)),organic carbon(OC),elemental carbon(EC),water-soluble ions,and up to 25 elements were determined.Investigation of the chemical compositions and potential sources revealed distinct differences between PM_(2.5) and PM_(10-2.5).The annual average mass concentrations were 55.5±25.5 and 25.9±15.7 ug/m^3 for PM_(2.5) and PM_(10-2.5),respectively.EC,OM(OM =OC×1.4),and ammonium sulfate comprised over ~82% of PM_(2.5),accounting for^29%,~27%,and ~25%,respectively,of the PM_(2.5) mass.Low OC/EC ratios(less than 1) for PM_(2.5) suggested that fresh diesel-engine exhaust was a major contributor.Seven sources were resolved for PM_(2.5) by positive matrix factorization(PMF) model,including vehicle emissions(~29%),secondary inorganic aerosols(~27%),waste incinerator/biomass burning(~23%),residual oil combustion(~10%),marine aerosols(~6%),industrial exhaust(~4%),and resuspended road dust(~1%).EC and OM comprised only ~19%of PM_(10-2.5).The average OC/EC ratio of PM_(10-2.5) was 7.8±14.2,suggesting that sources other than vehicular exhaust were important contributors.The sources for PM_(10-2.5) determined by the PMF model included ~20%traffic-generated resuspension(e.g.,tire dust/brake linear/petrol evaporation),~17% locally resuspended road dust,~17% marine aerosols,~12% secondary aerosols/field burning,and ~11%vehicle emissions. | Yan Cheng Shuncheng Lee Zhaolin Gu Kinfai Ho Yunwei Zhang Yu Huang Judith C.Chow John G.Watson Junji Cao Renjian Zhang | 2015 | Particuology2015，13，1： | 14 |
| 2 | Simulation of Low-Temperature Coal Tar Hydrocracking in Supercritical Gasoline显示文摘The aim of this paper was preliminary design of the process for low-temperature coal tar hydrocracking in supercritical gasoline based on Aspen Plus with the concept of energy self-sustainability.In order to ensure the correctness and accuracy of the simulation,we did the following tasks:selecting reasonable model compounds for low-temperature coal tar;describing the nature of products gasoline and diesel accurately;and confirming the proper property study method for each block by means of experience and trial.The purpose of energy self-sustainability could be possibly achieved,on one hand,by using hot stream to preheat cold stream and achieving temperature control of streams,and on the other hand,by utilizing gas(byproduct of the coal tar hydrocracking)combustion reaction to provide energy.Results showed that the whole process could provide a positive net power of about 609 kW·h for processing the lowtemperature coal tar with a flowrate of 2 268 kg/h.The total heat recovery amounted to 2 229 kW·h,among which 845kW·h was obtained from the gas combustion reaction,and 1 116 kW·h was provided by the reactor’s outlet stream,with the rest furnished by hot streams of the products gasoline,diesel and residue.In addition,the process flow sheet could achieve products separation well,and specifically the purity of product gasoline and diesel reached 97.2%and 100%,respectively. | Zhang Lei Liu Zongkuan Gu Zhaolin | 2013 | China Petroleum Processing & Petrochemical Technology2013，15，4： | 8 |
| 3 | Applications of membrane distillation technology in energy transformation process-basis and prospect显示文摘Membrane distillation technology is a new type of efficient separation technology that combines traditional distillation technology and membrane separation technology. In the study, applications of membrane distillation technology in thermal engineering and refrigerating engineering with typical energy transformation process were presented. Desorption and regeneration process of saline solution by vacuum membrane distillation was proposed on the basis of the concentration and separation properties of membrane distillation. Membrane distillation technology could be used in lithium bromide absorption refrigeration system, energy storage system, and the regeneration process of liquid desiccant solution in temperature-humidity independent control air-conditioning system. The aim of the applications was to use the low-grade energy such as waste heat, solar energy and geothermal energy adequately and to improve the available temperature difference of heat source. According to latent heat transfer and thermal conduction across the membrane in direct contact membrane distillation process, a novel membrane heat exchanger with both heat transfer and mass transfer processes was proposed. The heat exchanger could be used as the solution heat exchanger of lithium bromide absorption refrigeration system and as the special heat exchanger that recovered heat and pure water simultaneously. Some feasible process flows about the applications of membrane distillation technology to energy transformation process were listed and analyzed. Finally, future research emphases were indicated. | WANG ZanShe GU ZhaoLin FENG ShiYu LI Yun | 2009 | Chinese Science Bulletin2009，54，16： | 6 |
| 4 | Methods for large reciprocating compressor capacity control: A review based on pulse signal concept显示文摘Large reciprocating compressors are important equipment used in a wide range of process industries. Most of these compressors have huge power requirements and their capacity often needs to be regulated. Advanced technologies in compressor capacity control are effective approaches for saving large amounts of energy in process industries. This paper reviews the basic theories and the state of the art of the capacity control technologies. In particular, a compressor working procedure is first presented using an analogy to the pulse signal concept. Compressor capacity control methods are classified into pulse frequency modulation and pulse amplitude modulation from a perspective of pulse signal processing. The mechanisms and feasibility of some important methods, including dead volume variable control, partial-stroke and full-stroke suction valve opening, are reviewed. Based on the pulse signal concept, a duty cycle regulation method for capacity control is introduced, and the performance and implementation of the new method are compared with those of the existing suction valve opening methods. The duty cycle regulation method has integrated advantages over the other methods in terms of regulating precision, pressure stability, energy saving and reliability. All the suction valve opening methods can cause gas reflux, resulting in the so-called breathing effect. The breathing effect has negative effects on regulation performance and compressor security, which needs further investigation in the future. | GU ZhaoLin HOU XiongPo WANG ZanShe FENG ShiYu GAO XiuFeng LI Yun | 2011 | Chinese Science Bulletin2011，56，19： | 4 |
| 5 | Simulation of micro-behaviors including nucleation,growth,and aggregation in particle system显示文摘A new method for the solution of population balance equations(PBE) describing the micro-processes such as nucleation,growth,aggregation of particle swarms in a multiphase system is proposed.The method is based on the fixed pivot moment and allows arbitrary number of moments to be tracked si-multaneously.By expressing PBEs for both batch and continuous operations in a general form,and using weighted residual method to derive the moment equations,different moments can be tracked directly.The numerical density function is assumed to be a summation of several weighted Dirac Delta functions,and the integral and derivative terms in PBEs are transformed to a summation in order to reduce computational cost.Simulations of a batch nucleation-growth process and a continuous ag-gregation-growth process have demonstrated good agreement with the corresponding analytical solu-tions,with relative errors less than 108%.Simulation of a combined nucleation-growth-aggregation process,which does not have an analytical solution,is also included,so as to reproduce the mi-cro-behaviors of such a complex system,demonstrating the feasibility and reliability of this method. | GU ZhaoLin SU JunWei JIAO JianYing XU X Yun | 2009 | Science China Chemistry2009，52，2： | 4 |

| 11 | An efficient algorithm for detecting particle contact in non-uniform size particulate system显示文摘Algorithms for detecting particle collision play an important role in the discrete element method (DEM) for the simulation of granular flow systems since the time taken to detect the contact pairs usually occupies a considerable proportion of the total CPU time for the simulation. In this study, we developed a new octree algorithm called multi-octree algorithm, for detecting candidate contact pairs. The so-called multioctree algorithm adopts the topology of octree for detecting possible contacts, in which the particles are managed by hierarchical classification according to particle size and then mapped to different level nodes of an octree, instead of mapping all particles into the leaf nodes of an octree in Vemuri-octree algorithm. The present algorithm speeds up the detecting process by reducing the number of candidate particles for possible contacts. A non-uniform size particulate system with three particle sizes was simulated by the multi-octree and the Vemuri-octree algorithms simultaneously. The simulation results showed that the multi-octree algorithm is relatively insensitive to the volumetric fraction of particles and particle shapes, and takes much shorter time to find candidate particles for possible contacts than the Vemuri-octree algorithm for non-uniform size particulate systems. | Luyi Lu Zhaolin GU Kangbin Lei Sheng Wang Kiwamu Kase | 2010 | Particuology2010，8，2： | 1 |
| 12 | Technical measures to achieve a cleaner production mode for recycled paper mills显示文摘China’s paper production reached 79.8×10^(6) t in 2008 and ranked number one in the world.Because of its high consumption of water,energy and materials and its serious pollution,the present processes are not likely to be sustainable.An alternative,the closed Water Loop-Papermaking Integration(WLPI)method,is put forward in this paper.The WLPI method can be realized in a recycled paper mill by adding technologies and using recycled water.Many industrial case studies have shown that a large quantity of water,energy and materials can be saved,and the quantity of waste sludge and wastewater discharge was minimized by using the WLPI method.The design of the water reuse system,control of calcium hardness,water recycling and minimal waste sludge are discussed.Anaerobic technology plays an important role in the WLPI method to lower cost,energy use and waste.In the brown paper and coated white board production,zeroeffluent discharge can be realized.Fresh water consumption is only 1-2m^(3)·t^(-1).For the paper mills with deinking and bleaching processes,about 10 m^(3)·t^(-1) of fresh water and a similar amount of effluent discharge are needed.Power saving using anaerobic technology is 70%when recycled water is used in comparison with the conventional activated sludge process.Waste sludge can be decreased to about 5%of the initial process due to reuse of the waste sludge and the lower bio-sludge production of the anaerobic process. | Chao HE Zhaolin GU Shucheng YANG Jidong LIANG Weina DAI Yanling HE | 2010 | Frontiers of Environmental Science & Engineering2010，4，4： | 1 |

| 19 | Lattice Boltzmann Method for Conduction and Radiation Heat Transfer in Composite Materials显示文摘In this work,the utilization of lattice Boltzmann method(LBM)in the simulation of coupled conduction and radiation heat transfer in composite materials is studied.The novel D3Q30-LBM and D3Q38-LBM models are proposed for the simulation of radiative transfer equation(RTE).The LBM-LBM model,coupled finite volume method(FVM)and LBM are compared with the coupled FVM and discrete ordinate method(DOM)for 2D and 3D simulations.The results show that the original D3Q26-LBM is insufficient for the simulation of radiation,and both the D3Q30-LBM and D3Q38-LBM are close to the DOM for the RTE.The LBM can have large errors in the simulation of heat conduction when the relaxation time is large.Thus,its application in the composite materials is limited when the ratio between thermal conductivities of different components is large.The models with LBM for RTE can be more efficient than the FVM-DOM for the simulation of conduction-radiation heat transfer in composite materials.The FVM-D3Q30-LBM model is suggested because of its accuracy and efficiency. | TONG Zixiang LI Mingjia XIE Tao GU Zhaolin | 2022 | Journal of Thermal Science2022，31，3： | 1 |
