| 1 | Cellular structure of detonation utilized in propulsion system显示文摘How to confine a detonation in a combustor is a key issue of detonation applications in propulsion systems.Based on achieving schemes,detonations applied in the combustor,including pulse detonation wave(PDW),oblique detonation wave(ODW) and rotating detonation wave(RDW),are different from that described by the classic CJ theory in fine structures and its self-sustaining mechanisms.In this work,the cellular structures and flow fields of ODW and RDW were obtained numerically,and the fundamental characteristics and self-sustaining mechanisms of the detonations were analyzed and discussed.ODW front consists of three parts:the ZND-like front,the single-headed triple point front and the dual-headed triple point front.Cellular structures of RDW are heterogeneous,and the cell size near the outer wall is smaller than that near the inner wall. | ZHANG XuDong FAN BaoChun GUI MingYue PAN ZhenHua | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，10： | 2 |

| 4 | Beneficial Effects of Celastrol on Immune Balance by Modulating Gut Microbiota in Experimental Ulcerative Colitis Mice显示文摘Ulcerative colitis(UC)is a chronic inflammatory bowel disease caused by many factors including colonic inflammation and microbiota dysbiosis.Previous studies have indicated that celastrol(CSR)has strong anti-inflammatory and immune-inhibitory effects.Here,we investigated the effects of CSR on colonic inflammation and mucosal immunity in an experimental colitis model,and addressed the mechanism by which CSR exerts the protective effects.We characterized the therapeutic effects and the potential mechanism of CSR on treating UC using histological staining,intestinal permeability assay,cytokine assay,flow cytometry,fecal microbiota transplantation(FMT),16S rRNA sequencing,untargeted metabolomics,and cell differentiation.CSR administration significantly ameliorated the dextran sodium sulfate(DSS)-induced colitis in mice,which was evidenced by the recovered body weight and colon length as well as the decreased disease activity index(DAI)score and intestinal permeability.Meanwhile,CSR down-regulated the production of pro-inflammatory cytokines and up-regulated the amount of anti-inflammatory mediators at both mRNA and protein levels,and improved the balances of Treg/Th1 and Treg/Th17 to maintain the colonic immune homeostasis.Notably,all the therapeutic effects were exerted in a gut microbiota-dependent manner.Furthermore,CSR treatment increased the gut microbiota diversity and changed the compositions of the gut microbiota and metabolites,which is probably associated with the gut microbiota-mediated protective effects.In conclusion,this study provides the strong evidence that CSR may be a promising therapeutic drug for UC. | Mingyue Li Weina Guo Yalan Dong Wenzhu Wang Chunxia Tian Zili Zhang Ting Yu Haifeng Zhou Yang Gui Kaming Xue Junyi Li Feng Jiang Alexey Sarapultsev Huafang Wang Ge Zhang Shanshan Luo Heng Fan Desheng Hu | 2022 | Genomics, Proteomics & Bioinformatics2022，20，2： | 1 |

| 7 | Standing window of oblique detonation with pathological behaviour显示文摘Standing of an Oblique Detonation Wave(ODW)on a wedge within combustor is the prerequisite of thrust generation for ODW engine which is regarded as a novel and conceptual propulsion device with hypersonic flight Mach number.Usually a standing window of ODW is defined as the wedge angle ranged from the ODW detached angle from wedge(upper limit)to the angle that a Chapman-Jouguet(CJ)detonation occurs(lower limit).For pathological detonation cases,however,the CJ detonation cannot be achieved,and thus the lower limit of the standing window of ODW should be revisited.In present study,two types of reactions in hypersonic incoming flow that include the behavior of pathological detonation,that is,the single-step irreversible reaction with mole variation and the two-step irreversible reactions with exothermic process followed by endothermic process,have been used for studying standing behavior of ODW.The steady detonation polar analysis of ODW is carried out for both reaction systems.The results reveal that the reaction with more mole decrement and the reactions with stronger endothermic process show the pathological detonation feature and therefore modify the lower limit of standing window of ODW.Three equivalent parameters are proposed to quantitatively measure the standing window range of ODW from points of view of thermodynamics,Mach number of incoming flow and heat effect of reactions.It is found that the standing window of ODW is determined by the specific heat ratio,the overdrive degree of detonation and the endothermic level of the hypersonic incoming flow,regardless of whether the detonation is pathological or not. | Zhuo XU Gang DONG Zhenhua PAN Mingyue GUI | 2021 | Chinese Journal of Aeronautics2021，34，5： | 0 |
| 8 | Numerical study of the turbulent channel flow under space-dependent electromagnetic force control at different Reynolds numbers显示文摘In this paper, the control of turbulent channel flow by space-dependent electromagnetic force and the mechanism of drag reduction are investigated with the direct numerical simulation(DNS) methods for different Reynolds numbers. A formulation is derived to express the relation between the drag and the Reynolds shear stress. With the application of optimal electromagnetic force, the in-depth relations among characteristic structures in the flow field, mean Reynolds shear stress, and the effect of drag reduction for different Reynolds numbers are discussed. The results indicate that the maximum drag reductions can be obtained with an optimal combination of parameters for each case of different Reynolds numbers. The regular quasi-streamwise vortex structures, which appear in the flow field, have the same period with that of the electromagnetic force.These structures suppress the random velocity fluctuations, which leads to the absolute value of mean Reynolds shear stress decreasing and the distribution of that moving away from the wall. Moreover, the wave number of optimal electromagnetic force increases,and the scale of the regular quasi-streamwise vortex structures decreases as the Reynolds number increases. Therefore, the rate of drag reduction decreases with the increase in the Reynolds number since the scale of the regular quasi-streamwise vortex structures decreases. | Daiwen JIANG Hui ZHANG Baochun FAN Zijie ZHAO Jian LI Mingyue GUI | 2019 | Applied Mathematics and Mechanics(English Edition)2019，40，4： | 0 |
