In the present study, Detached Eddy Simulation is applied to the supersonic axisymmetric base flow. Computations are done on coarse and fine unstructured grids to examine the influence of grid refinement on flow predictions. The final results are compared with available experimental data of Herrin and Dutton, which includes boundary layer velocity profile, base pressure, centerline velocity profile, Mach and turbulent kinetic energy distributions. The influence of grid refinement is observed and the reasons are discussed.
