| 摘 要： | 基于车用增压器涡轮的进口压力和温度是脉动变化的,本文采用Numeca软件求解进口边界条件为给定脉动总压总温的三维非定常Navier-Stokes方程组,并对相同进口条件下的涡轮转子内部流场进行分析。研究结果表明,脉冲进气条件下的涡轮特性具有强烈的非定常特征。

Investigation on the Effect of Pulsating Inlet Flow on the Flow Field of Radial Turbine Rotor Passages |
| |
| Abstract: | The inlet pressure and temperature experienced by vehicle turbocharger turbines are pulsative.Accordingly this paper aims at solving 3D unsteady N-S equation groups under pulsating flow condition,the flow field of radial turbine rotor passages with identical stage inlet condition was analyzed.The result show that,the turbine performance under pulsating inlet flow contiton is of highly unsteady features. |
