Abstract

Abstract: A three-dimensional high-precision RANS numerical solver was developed for the complex internal viscous flow in transonic turbomachinery. The Rotor 67 transonic compressor rotor was numerically simulated by using FVS scheme and AUSM + scheme combined with various limiters. The calculation results of these schemes were analyzed and compared with the experimental results. The results showed that AUSM + scheme has smaller numerical viscosity and higher simulation accuracy of boundary layer than FVS scheme. The Hemker limiter has the best overall performance. The viscous resolution of the Van Albada limiter is slightly lower than that of the Hemker limiter. The Minmod limiter has poor ability to capture the flow separation phenomenon. The Van Leer limiter is easy to introduce the dispersion error.

摘要： 针对跨声速叶轮机械复杂内部粘性流动，开发了全三维高精度RANS数值求解器。分别采用FVS格式与AUSM+格式结合多种限制器对Rotor 67跨声速压气机转子进行数值模拟，分析和比较了各格式的计算效果并与试验结果对比。结果表明：与FVS格式相比，AUSM+格式的数值粘性更小，边界层的模拟精度更高；Hemker限制器的综合表现最优，Van Albada限制器的粘性分辨率略低于Hemker限制器，Minmod限制器对流动分离现象的捕捉能力较差，Van Leer限制器容易引入色散误差。
