Detached Eddy Simulation of Flow over a Periodic Dune


Detached Eddy Simulation (DES) of periodic flow (outlet is fed back to the inlet) over a 2-D asymmetric dune. Starting condition (t=0s) is the dune modelled using a Reynolds Averaged Navier-Stokes (RANS) model used to initialize the model. Modelled in OpenFOAM using the Spalart-Allmaras delayed detached eddy simulation (DDES) model. This 13 second simulation took 12 hours to compute running in parallel on 4 CPUs.
