Wall-Modeled Large Eddy Simulation is an attractive option for complex high Reynolds number turbulent flows owing to its reduced cost and reasonably good accuracy when compared to wall-resolved simulations. Commonly used Reynolds-Averaged Navier-Stokes models fail to accurately predict separated flows and thus scale-resolving simulations are becoming increasingly popular for such flows. While different wall models yield good predictions for attached flows, separated flows serve as more challenging test cases. We assess the performance of the equilibrium (Kawai & Larsson, Phys. of Fluids, Vol. 24, No. 1, 2012) and nonequilibrium (Park & Moin, Phys. of Fluids, Vol. 26, No. 1, 2014) wall models for the transonic axisymmetric flow past a bump corresponding to experiments of Bachalo & Johnson (AIAA J., Vol. 23, No. 3, pp. 437-443, 1986). Good agreement is observed with experiment for the wall-pressure distribution, separation and reattachment locations. Reasonable agreement is observed for the mean velocity and Reynolds stresses in the separation region. The effect of wall model on the results are discussed.
