Large Eddy Simulation (LES) and Detached Eddy Simulation (DES) are applied to prediction and investigation of the ow around a sphere. DES is a hybrid approach in which the closure is a simple modi cation to the Spalart-Allmaras model, reducing to Reynolds-Averaged Navier-Stokes (RANS) in attached regions, and LES away from the wall . Calculations are performed at a Reynolds number, Re = 10, in the sub-critical regime where there is a laminar boundary layer separation from the sphere. A fth… CONTINUE READING
