Numerical Investigation on Unsteady Pressure Oscillation of Gas-Solid Two-Phase Turbulent Flow
与发动机振荡燃烧相关的气固两相流中的压力脉动现象长期以来备受关注.为了解发动机气固两相流动中的非定常压力脉动特性,以典型的后台阶气固两相流动为研究对象,使用发展的自适应湍流模拟(Self-adaptive turbulence eddy simulation,SATES)和离散相模型(Discrete phase model,DPM)相结合的方法,对两相流场进行了三维非定常高精度数值计算.以实验数据作为参考验证了计算方法的精度和可靠性.通过将两相…查看全部>>
Relevant to thermoacoustic combustion instability in engines,the pressure oscillations in gas-solid two-phase turbulent flow have long been a topic of great concerns.To understand the pressure oscillation characteristics in gas-solid two-phase flow,three-dimensional unsteady numerical calculations are conducted for typical two-phase gas-solid backstep flow using the combined self-adaptive turbulence eddy simulation(SATES)and discrete phase model(DPM)method.T…查看全部>>
