1Simulation of aerodynamic performance affected by vortex generators on blunt trailing-edge airfoils显示文摘An investigation was carried out by numerical simulation on a wind turbine airfoil and a blunt trailing-edge airfoil with and without vortex generators (VGs), and the performance of the airfoils was analyzed. By the simulation of airfoil DU 91-W2-250 it was verified that the numerical method and model were credible. Based on this airfoil, a new one with a blunt trailing edge of 6% chord was blended by symmetrically adding thickness, and its characteristics curves were obtained through computing at key angles of attack. Additionally, the pressure distribution on blended airfoil was analyzed by comparing to the airfoil without blend. The interaction of streamwise vortices induced by VGs with trailing vortex or separation vortex was considered, followed by the uncovery of how VGs can suppress the boundary layer separation.YANG Ke1,2,ZHANG Lei1,3 & XU JianZhong1,2 1 Institute of Engineering Thermophysics,Chinese Academy of Sciences,Beijing 100190,China 2 Key Laboratory of Wind Energy Utilization,Chinese Academy of Sciences,Beijing 100190,China 3 Graduate School of Chinese Academy of Sciences,Beijing 100190,China 2010Science China(Technological Sciences)2010,53,1:15
2Complex Flow for Wing-in-ground Effect Craft with Power Augmented Ram Engine in Cruise显示文摘Power augmented ram (PAR) engine is a popular equipment to reduce the requirement of power for takeoff and improve aerodynamic performance.To provide detailed insight into the aerodynamic characteristics of wing-in-ground effect (WIG) craft with PAR engine,numerical simulations are carried out on WIG craft models in cruise.Simplified engine models are applied to the simulations.Two cruise modes for PAR engine are considered.The aerodynamic characteristics of the WIG craft and other features are studied.Comparisons with WIG craft model without PAR show that shutoff of PAR engine results in an increase in drag and less change in lift.Accordingly for the work of PAR engine,the air flow blown from the engine accelerates the flow around the upper surface and a high-speed attached flow near the trailing edge is recorded.With the schemed PAR flow,more suction force is realized and the flow features over the wing vary noticeably.It is also shown that the Coanda effect,provided with an attached flow,introduces an appropriate and practical flow mode for WIG craft with PAR engine in cruise.The results refresh our understanding on aerodynamic characteristics of WIG craft.Yang Zhigang,Yang Wei Shanghai Automotive Wind Tunnel Center,Tongji University,Shanghai 201804,China 2010Chinese Journal of Aeronautics2010,23,1:7

5Association of the GNAS1 T393C polymorphism with tumor stage and survival in gastric cancer显示文摘AIM:To analyze the impact of the GNAS1 T393C polymorphism on prognosis and histopathology of gastric cancer.METHODS:Genomic DNA was extracted from paraffinembedded tissues of 122 patients with primary gastric carcinoma and from the blood of 820 healthy white individuals.Allelic discrimination was performed by quantitative real-time polymerase chain reaction.Genotyping was correlated with histopathologic parameters and with overall survival according to the Kaplan-Meier approach and with multivariate analysis by multiple stepwise regression.RESULTS:Thirty-nine(32%) patients displayed a CC genotype,57(46.7%) a CT genotype and 26(21.3%) a TT genotype.The frequency of the C allele(fC) in the patient group was 0.55,which was not signif icantly different from that of healthy blood donors.The distribution was compatible with the Hardy-Weinberg equilibrium.Analysis of clinicopathological parameters did not show any signif icant correlation of the T393C genotype with gender(P=0.50),differentiation(P=0.29),pT-category(P=0.19),pN-category(P=0.30),pM-category(P=0.25),R-category(P=0.95),the classifications according to WHO(P=0.34),Laurén(P=0.16),Goseki(P=1.00) and Ming(P=0.74).Dichotomization between C+(CC+CT) and C-genotypes(TT),however,revealed signif icantly more advanced tumor stages(P=0.023) and lower survival rates(P=0.043) for C allele carriers.CONCLUSION:The present study provides strong evidence to suggest that the GNAS1 T393C allele carrier status influences tumor progression and survival in gastric cancer with higher tumor stages and a worse outcome for C allele carriers.Hakan Alakus Stefan P Mnig Ute Warnecke-Eberz Gül Alakus Günther Winde Uta Drebber Klaus J Schmitz Kurt W Schmid Kathrin Riemann Winfried Siffert Elfriede Bollschweiler Arnulf H Hlscher Ralf Metzger 2009World Journal of Gastroenterology2009,15,48:3
6Development of CO2 Selective Poly(Ethylene Oxide)-Based Membranes: From Laboratory to Pilot Plant Scale显示文摘气体膜分离法是从气流中分离二氧化碳(CO_2)的最有前途的技术之一。例如,采用该技术对燃烧过程中的烟气进行处理,以达到CO_2捕集和封存的目的。聚环氧乙烷嵌段共聚物能够很好地应用于膜分离技术,如Pebax~?或Poly Active^(TM)。本文采用Poly Active^(TM)作为复合薄膜的选择层。在环境温度下,当CO_2/N_2选择性超过55时,这种薄膜的CO_2渗透率高达4 m^3(STP)·m^(–2)·h^(–1)·bar^(–1)(注:1 bar=105 Pa)。这种薄膜可以按照中试规模进行生产放大,而且可以设计成不同的平面膜组件。采用单一气体渗透数据作为唯一的实验输入而开发出的仿真工具可以准确预测这种膜组件的性能。在不同的中试研究中,我们利用烟气和沼气作为原料气流,反复检测这些膜和膜组件的性能。Poly Active^(TM)在检测中显示出了稳定的分离性能,表明Poly Active^(TM)非常适用于作为膜材料进行工业规模气体处理。Torsten Brinkmann Jelena Lilleparg Heiko Notzke Jan Pohlmann Sergey Shishatskiy Jan Wind Thorsten Wolff 2017Engineering2017,3,4:3
