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-ω) 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 k-ω 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.
