　　The present study aims to analyze the compressibility modification effects for conventional RANS(Reynolds-Averaged Navier-Stokes)simulation for high-subsonic jet flow,and furthermore the jet noise analysis.Two compressibility modifications are introduced for the widely-used standard k-ε turbulence model in jet flow simulation.

除尘管道粉尘运移及沉积研究
采用欧拉–拉格朗日方法，并考虑气相与颗粒相的双向耦合，对管道内不同工况下气固多相流动进行了数值模拟。基于颗粒与壁面碰撞过程中的能量分析，建立了粉尘沉积–回弹模型，即粉尘颗粒与壁面碰撞后，法向速度所对应的动能大于壁面的黏附能才会回弹，否则会被壁面捕获。由此得出了粉尘颗粒的沉积准则以及颗粒碰撞后的回弹速度。
