Simulation of unsteady isotropic turbulent flows on unstructured meshes using edge-based algorithms

The paper considers the results of investigation of edge-based reconstruction (EBR) schemes applied to far from walls turbulent flows simulation using scale-resolving approaches. The simulations were done for two canonical problems. The first one is Taylor–Green vortex evolution at Reynolds number Re=1600. Also the decay of homogenous isotropic turbulence problem at Re=1638 is considered. Computations were carried out using different unstructured meshes with varying resolution. The evaluation of results of simulations was done based on comparison with corresponding reference data and the results of direct numerical simulation.
