| 1 | Numerical Investigation of Centerline Curvature Effects on a Compact S-shaped Intake显示文摘Taking into account stealth, structure and maintenance, ultra-compact S-shaped intake has been widely used in modern vehicles. In this paper a series of steady numerical simulation were carried out to investigate the complex flow mechanism in s-shaped intake, particular attention was given to examining the effect of centerline curvature on the performance and flowfield of an ultra-compact S-shaped intake. In order to validate the multi-block model, the computational results for Royal Aircraft Establishment intake 2129-M2129 which had modest centerline curvature distribution were corrected with available experimental test data. The numerical simulation results agreed fairly well with the experimental data, and the computational method was then used to investigate the effects of different centerline curvature distributions on performance and flow field in compact S-shaped intake. Detailed analyses of the flow visualization had exposed the different flow topologies between the cases with different centerline curvature. It was found that different centerline curvature distributions changed the initial location and the size of separation bubble, as well as the strength of two counter-rotating vortices at the entrance of engine. | Enliang Huang Shengfeng Zhao Zhijun Lei Jianxiong Kang Xingen Lu Junqiang Zhu | 2012 | Journal of Thermal Science2012，21，5： | 1 |
| 2 | Design and high-strength origin of novel (CoFeNi)_(80)Ti_(5)V_(15) medium entropy alloy with “fcc + L1_(2) ”structure显示文摘1.Introduction The multi-component high entropy alloys(HEAs)or medium entropy alloys(MEAs)attract reseachers’extensive attention,in particular,the single-face center cubic(fcc)HEAs or MEAs due to their some advantages,such as excellent ductility[1,2],good corrosion resistance[3]and high radiation tolerance[4].However,their strength is commonly insufficient for engineering applica-tions.Recently,many investigations are ongoing to improve their strength by traditional strengthening mechanisms,like fine-grained strengthening[5,6],solid strengthening[6-8],strain strengthening[9],polyphase strengthening[10-12],and precipitation strength-ening[13-15].Among these strengthening mechanisms,the co-herent L1_(2)-type nanoparticles precipitation strengthening has been proven to be a very effective way to improve their strength[13-15]. | Lei Wang Xinyuan Wu Yuan Wu Gang Liu Zhenhua Han Yunpeng Zhang Yanning Su Shengfeng Kang Jun Shen Guojun Zhang | 2023 | Journal of Materials Science & Technology2023，，18： | 0 |
