摘要：
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. © 2020, Editorial Department of Journal of Propulsion Technology. All right reserved.
