| 2 | Measurement of laminar burning velocities and analysis of flame stabilities for hydrogen-air-diluent premixed mixtures显示文摘The laminar burning velocities and Markstein lengths of the hydrogen-air-diluent mixtures were meas-ured at different equivalence ratios (0.4―1.5), different diluents (N2, CO2 and 15%CO2+85%N2) and di-lution ratios (0, 0.05, 0.10 and 0.15) by using the outwardly expanding flame. The influences of flame stretch rate on the flame propagation characteristics were analyzed. The results show that both the laminar burning velocities and the Markstein lengths of the hydrogen-air-diluent mixtures decrease with the increase of dilution ratio. The decrease in Markstein lengths means that adding diluents into the hydrogen-air mixtures will decrease the diffusional-thermal instability of the flame front. For a specified dilution ratio, the laminar burning velocities give their maximum values at an equivalence ratio of 1.8. The Markstein lengths increase with the increase of the equivalence ratio monotonously regardless of the diluents. The study shows that CO2 as the diluent has a greater impact on the laminar flame speed and the flame front stability than N2 as the diluent. | HU ErJiang HUANG ZuoHua HE JiaJia JIN Chun MIAO HaiYan WANG XiBin | 2009 | Chinese Science Bulletin2009，54，5： | 4 |
| 3 | Effect of 2,5-dimethylfuran addition on ignition delay times of n-heptane at high temperatures显示文摘The shock tube autoignition of 2,5-dimethylfuran (DMF)/n-heptane blends (DMF)/n-100%, by mole fraction) with equivalence ratios of 0.5, 1.0, and 2.0 over the temperature range of 1200-1800 K and pressures of 2.0 atm and 10.0 atm were investigated. A detailed blend chemical kinetic model resulting from the merging of validated kinetic models for the components of the fuel blends was developed. The experimental observations indicate that the ignition delay times nonlinearly increase with an increase in the DMF addition level. Chemical kinetic analysis including radical pool analysis and flux analysis were conducted to explain the DMF addition effects. The kinetic analysis shows that at lower DMF blending levels, the two fuels have negligible impacts on the consumption pathways of each other.As the DMF addition increases to relatively higher levels, the consumption path of n-heptane is significantly changed due to the competition of small radicals, which primarily leads to the nonlinear increase in the ignition delay times of DMF/n-heptane blends. | Zhenhua GAO Erjiang HU Zhaohua XU Geyuan YIN Zuohua HUANG | 2019 | Frontiers in Energy2019，13，3： | 4 |
| 4 | Stifness modeling and analysis of a novel 4-DOF PKM for manufacturing large components显示文摘Faster response to orientation varying is one of the outstanding abilities of a parallel kinematic machine(PKM).It enables such a system to act as a reconfgurable module employed to machine large components effciently.The stiffness formulation and analysis are the beforehand key tasks for its parameters design.A novel PKM with four degrees of freedom(DOFs)is proposed in this paper.The topology behind it is 2PUS–2PRS parallel mechanism.Its semianalytical stiffness model is frstly obtained,where the generalized Jacobian matrix of 2PUS–2PRS is formulated with the help of the screw theory and the stiffness coeffcients of complicated components are estimated by integrating fnite element analysis and numerical ftting.Under the help of the model,it is predicted that the property of system stiffness distributes within the given workspace,which features symmetry about a certain plane and is also verifed by performing fnite element analysis of the virtual prototype.Furthermore,key parameters affecting the system stiffness are identifed through sensitivity analysis.These provide insights for further optimization design of this PKM. | Li Yonggang Zhang Erjiang Song Yimin Feng Zhiyou | 2013 | Chinese Journal of Aeronautics2013，26，6： | 3 |
| 5 | 澳大利亚上空COSMIC掩星廓线的反演显示文摘基于几何光学反演方法,由附加相位延迟序列出发,对2007年6月6日发生在澳大利亚上空的一次COSMIC掩星事件进行了反演。将反演得到的折射角、折射率、干温与湿度廓线分别与COSMIC数据分析与管理中心(COSMIC data analysis and archive center,CDAAC)的相应产品进行了比较。结果表明,两者在低对流层存在较显著的差异。以距离该掩星地点300 km以内、观测时间差异2 h以内的无线电探空资料为参照,反演的折射率廓线与CDAAC的折射率廓线在低对流层都存在一定的误差。对于该掩星事件,CDAAC通过变分法反演的湿度廓线并不比本文的反演结果更接近探空廓线;在1 km以下,其变化趋势甚至与探空结果相矛盾。 | 徐晓华 Zhang Kefei Fu Erjiang 罗佳 | 2008 | 武汉大学学报(信息科学版)2008，33，8： | 3 |

| 9 | Numerical study on combustion of diluted methanol-air premixed mixtures显示文摘The effect of nitrogen dilution on the premixed combustion characteristics and flame structure of laminar premixed methanol-air-nitrogen mixtures are analyzed numerically based on an extended methanol oxidation mechanism. The laminar burning velocities, the mass burning fluxes, the adiabatic flame temperature, the global activation temperature, the Zeldovich number, the effective Lewis number and the laminar flame structure of the methanol-air-nitrogen mixtures are obtained under different nitrogen dilution ratios. Comparison between experiments and numerical simulations show that the extended methanol oxidation mechanism can well reproduce the laminar burning velocities for lean and near stoichiometric methanol-air-nitrogen mixtures. The laminar burning velocities and the mass burning fluxes decrease with the increase of nitrogen dilution ratio and the effect is more obvious for the lean mixture. The effective Lewis number of the mixture increases with the increase of nitrogen dilution ratio, and the diffusive-thermal instability of the flame front is decreased by the nitrogen addition. Nitrogen addition can suppress the hydrodynamic instability of methanol-air-nitrogen flames. The decrease of the mole fraction of OH and H is mainly responsible for the suppressed effect of nitrogen diluent on the chemical reaction in the methanol-air-nitrogen laminar premixed flames, and the NOx and formaldehyde emissions are decreased by the nitrogen addition. | Zheng JianJun Zhang ZhiYuan Huang ZuoHua Hu ErJiang Tang ChengLong Wang JinHua | 2010 | Chinese Science Bulletin2010，55，9： | 1 |
