Abstract: Abstract A Delayed Detached Eddy Simulation (DDES) of a rotationally symmetric free jet is performed with the scientific in-house code TASCOM3D (Turbulent All Speed Combustion Multigrid 3D). The DDES is a hybrid RANS/LES method that employs the RANS approach in the near-wall region and LES modeling otherwise. The transition is achieved by filtering depending on the grid spacing. To preserve the RANS mode in the boundary layer an appropriate blending function is used. The investigated experiment is a supersonic Ma 1.8 jet exiting a nozzle into ambient conditions. The simulation results for the axial velocity, temperature, density and density fluctuations are compared to measured values. Several simulations have been performed to analyze the effect of the modeling constant C DES , grid refinement, and the addition of artificial fluctuations in the boundary layer that are not created inherently in the used approach. The overall agreement between experiment and simulation is quite satisfying although the transition is apparently predicted too far upstream in all simulations.
