| 摘 要： | 针对燃气轮机内流高温、变组分的问题,在已有高精度、高分辨率算法的基础上发展了一套高速可压缩多组分流动数值计算方法。为了解决高速多组分流动中存在的特殊问题,采用全组分方程隐式联立求解和扩散速度修正方法提高了组分的守恒性和计算精度;通过求解比热比输运方程,消除了间断附近的压力振荡。经过多个典型算例验证,说明了本文方法的有效性,从而为下一步进行新一代燃气轮机内部真实流动的模拟奠定了基础。

| Abstract: | A numerical simulation method for high speed compressible multi-component flow was proposed to solve the high temperature and multi-species flow in future generation gas turbines. Implicit scheme for complete species equations and diffusion velocity correction method were used to improve the accuracy and conservation of mass fraction for each species.An additional transport equation related to specific heat ratio was solved to avoid nonphysical pressure oscillation around contact interface.The code was vali... |
