| 1 | 高压气淬均匀性研究显示文摘高压气淬具有纯对流传热、易于控制、工件淬火后无需清洗和对环境影响小等优点。然而,典型的气淬设备显示出淬火料盘与工件之间的气流不均匀,导致工件的最终性能产生差异。业已发现,料盘的逆向气流布置是决定局部气流状态和热量传递的关键因素。尽管气流的主要部分在料盘与炉壁之间流动,对淬火过程不起作用,但是由料盘引起的流动阻力所产生的压降决定了淬火冷却强度。采用一种能较快收敛的多尺度模型对工业用高压气淬炉的内部流场进行了模拟,并通过速度测量和气流可视化技术对试验用淬火炉的内部气流进行了试验研究。最后,对圆柱体工件的双室真空炉淬火进行了模拟结果的验证,揭示了不同的逆向流速分布对淬火结果的影响。报道了多尺度模拟方法和流动过程的研究结果,并概述了对气淬工艺优化的指导性建议。 | R R Schmidt U Fritsching 顾剑锋 | 2012 | 热处理2012，27，2： | 4 |

| 3 | Sludge thickening in a wastewater treatment plant using a modified hydrocyclone显示文摘The main application of hydrocyclones in most industry sectors is the separation of particles from liquids.For thickening,however,the separation properties of the cyclone should be adjustable,which requires a different operating mode.Therefore,we investigated an add-on thickening module,consisting of a conical plug and a secondary vortex finder in the underflow of the hydrocyclone.Laboratory scale experiments are carried out to investigate the function of the concept of annular gap modification by the use of the thickening module.In the second step,we transferred this concept to industrial scale for field tests at a municipal wastewater treatment plant.In the field tests,geometrical properties(annular gap modification)and operational parameters(volume flow rate,sludge type)were investigated.The results show that thickening in terms of increasing the total solids content of sludge is possible with the modified hydrocyclone.In the field tests,a thickening factor(total solids content of thickened sludge related to feed sludge)of 1.31(average)was reached for digested sludge.Hence,a hydrocyclone could be a promising addition in wastewater treatment plants for dewatering of sludge. | Thomas Senfter Lukas Fritsch Manuel Berger Tobias Kofler Christian Mayerl Martin Pillei Michael Kraxner | 2021 | Carbon Resources Conversion2021，4，1： | 3 |
| 4 | Particle penetration in fiber filters显示文摘Particle separation from gases is an important unit operation in manifold industrial applications,such as those conducted in environmental protection.For analysis of particle penetration and separation in fiber filters,standard dust particles (Al2O3)were loaded in the gas flow of a filter test facility and deposited within new and uncharged fiber filters.The loaded filters were analyzed by micro-computer tomography and scanning electron microscopy.Three-dimensional tomograms of the samples show an exponential decay of the penetration depth of the particles.This dependency is confirmed by simulations conducted using the discrete element method coupled with computational fluid dynamics within unloaded and loaded fiber structures.Microscale processes of particle separation at the fibers as well as the filtration efficiency and time-dependent filtering process are derived from the simuiations.Local particle clustering in the filter medium and partial filter clogging are thus identified. | Norbert Riefler Martina Ulrich Marko Morshaiuser Udo Fritsching | 2018 | Particuology2018，16，5： | 3 |

| 14 | Microbiological screenings for infection control in unaccompanied minor refugees: the German Armed Forces Medical Service's experience显示文摘Background:The German Military Medical Service contributed to the medical screening of unaccompanied minor refugees(UMRs)coming to Germany in 2014 and 2015.In this study,a broad range of diagnostic procedures was applied to identify microorganisms with clinical or public health significance.Previously,those tests had only been used to screen soldiers returning from tropical deployments.This instance is the first time the approach has been studied in a humanitarian context.Methods:The offered screenings included blood cell counts,hepatitis B serology and microscopy of the stool to look for protozoa and worm eggs as well as PCR from stool samples targeting pathogenic bacteria,protozoa and helminths.If individuals refused certain assessments,their decision to do so was accepted.A total of 219 apparently healthy male UMRs coming from Afghanistan,Egypt,Somalia,Eritrea,Syria,Ghana,Guinea,Iran,Algeria,Iraq,Benin,Gambia,Libya,Morocco,Pakistan,and Palestine were assessed.All UMRs who were examined at the study department were included in the assessment.Results:We detected decreasing frequencies of pathogens that included diarrhoea-associated bacteria[Campylobacter(C.)jejuni,enteropathogenic Escherichia(E.)coli(EPEC),enterotoxic E.coli(ETEC),enteroaggregative E.coli(EAEC),enteroinvasive E.coli(EIEC)/Shigella spp.),Giardia(G.)duodenalis,helminths(comprising Schistosoma spp.,Hymenolepis(H.)nana,Strongyloides(S.)stercoralis]as well as hepatitis B virus.Pathogenic microorganisms dominated the samples by far.While G.duodenalis was detected in 11.4%of the assessed UMRs,the incidence of newly identified cases in the German population was 4.5 cases per 100,000 inhabitants.Conclusion:We conclude that the applied in-house PCR screening systems,which have proven to be useful for screening military returnees from tropical deployments,can also be used for health assessment of immigrants from the respective sites.Apparently healthy UMRs may be enterically colonized with a broad variety of pathogenic and apathogenic microorganisms.Increased colonization rates,as shown for G.duodenalis,can pose a hygiene problem in centralized homes for asylum seekers. | Winfried Maaβen Dorothea Wiemer Claudia Frey Christina Kreuzberg Egbert Tannich Rebecca Hinz Andreas Wille Andreas Fritsch Ralf Matthias Hagen Hagen Frickmann | 2018 | Military Medical Research2018，5，1： | 2 |
| 15 | Dynamic flowsheet simulation of re-entrainment from particle layers formed inside electrostatic precipitators显示文摘Electrostatic precipitators clean away the particulate matter of exhaust gases in manifold industrial processes.Parameter studies of particle separation in the size range of several 100 nm to 25μm is of particular interest for the prediction of precipitation efficiencies and emissions.Models typically cover the transport of particles towards walls of the precipitator.However,no model yet covers the possible re-entrainment of particles from layers formed at the walls back into the gas flow.This study presents the implementation of a new time-resolving model for electrostatic precipitation utilizing a re-entrainment model.Experimental data support the results of modelling.The model uses a statistical approach based on properties of the particulate layer forming at the precipitator walls.The model is used for the analysis of the redispersion of particles in a laboratory-scale electrostatic precipitator(Sander,Gawor,&Fritsching,2018).Results show reduced precipitation efficiencies for particles larger than 5μm as particles have higher kinetic impact energies and lower bounding energy at the layer surface.Time dynamics reveal a steady-state behavior of the separation for CaCO3(limestone,trademark'Ulmer WeissR')while Al2O3(trademark'Pural NFR')precipitation is affected by layer buildup at the walls increasing over several minutes. | Soren Sander Udo Fritsching | 2020 | Particuology2020，18，6： | 2 |
