Modelling of fully separated flow past a circular cylinder: Problems and best practice

This paper gives a draft overview of the elaborated strategy for a reliable simulation of a subcritical incompressible viscous flow past a circular cylinder by the means of the commercial Software ANSYS CFX. It is motivated by its relevance to serve as a general flow prototype past a bluff body, which is an issue of considerable engineering interest, and is focused on the computational specifics of the topic. The flow separation is investigated by the means available in the ANSYS CFX Reynolds Averaged Navier-Stokes Simulations (RANS) method as the Shear Stress Transport model is employed.
