Instead, a simple mesh is used and the geometry is projected onto it by a scalar indicator field and the effect of the solid phase on the flow is accounted for by adjustment of governing equations. Utilization of an IBM is advantageous in geometry optimizations where it saves time on mesh generation and reduces other mesh-related difficulties. In our past work, we have used our custom IBM variant, the hybrid fictitious domain-immersed boundary (HFDIB) method [1], to perform a topology optimization under laminar flow conditions. However, in engineering practice, the flow is usually turbulent and to perform a topology optimization under turbulent flow conditions, the HFDIB need to be coupled with a feasible turbulence modeling approach. In this work, we present achieved results in development of a HFDIBRANS method that is a combination of the HFDIB method and the Reynolds-averaged turbulence modeling approach with wall functions. In particular, we implemented the k-ω, k-ε, k-ω SST and realizable k-ε models with wall functions for k, ω and ε.
