Abstract The Menter Shear Stress (SST) turbulence model has been added to FEARCE, a Los Alamos National Laboratory Finite Element reactive flow code for solution of fluid-structure interaction, and turbulent reactive flow with multiphases. The SST model is an addition to the Reynolds Averaged Navier-Stokes (RANS) model of Wilcox (k-) in FEARCE where the primary focus of the method is the application of unsteady flow particularly related to internal combustion engines. The solution algorithm uses a stabilized Petrov-Galerkin method in a Predictor-Corrector Split (PCS) scheme which is designed to handle all flow regimes from low-speed incompressible flow through subsonic and supersonic flow. The newly added SST is presented in comparison to the Wilcox - model where two benchmarks problems are analyzed with solutions for incompressible flow with heat transfer for validation of the model and code for lower-speed flow regimes.

有限元 Menter Shear Stress 湍流传输模型

摘要 Menter 剪切应力 (SST) 湍流模型已添加到 FEARCE 中，FEARCE 是洛斯阿拉莫斯国家实验室有限元反应流代码，用于解决流固耦合和多相湍流反应流。SST 模型是 FEARCE 中 Wilcox (k-) 雷诺平均纳维-斯托克斯 (RANS) 模型的补充，其中该方法的主要重点是非定常流动的应用，特别是与内燃机相关的应用。求解算法在预测器-校正器分离 (PCS) 方案中使用稳定的 Petrov-Galerkin 方法，该方案旨在处理从低速不可压缩流到亚音速和超音速流的所有流态。
