Abstract: A mathematical model and numerical algorithm for unsteady turbulent flows is considered. The IDDES approach based on the turbulence model of Spalart and Allmaras (SA) is applied. Performance of the computational algorithm, based on the LU-SGS–GMRES combined method, and scheme dissipation properties regarding convective fluxes discretization is investigated in order to choose optimal scheme for vortex-resolving IDDES modelling. Numerical solution of the unsteady turbulent boundary layer formation in rectangular periodic channel for supersonic flow is carried out to perform verification and validation of the IDDES approach realization and to study features of hybrid time marching schemes.
Keywords: Spalart-Allmaras turbulence model, LU-SGS–GMRES algorithm, IDDES approach, hybrid time marching scheme, turbulent boundary layer.
