Abstract: Abstract Due to the large disparity of length and time scales in rocket combustors corresponding LES are highly time consuming. Steps towards simulating rocket combustion engines with affordable LES with the compressible, implicit combustion code TASCOM3D are presented. DES-family (DES, DDES, iDDES) models are compared and evaluated on two simple test cases: the turbulent isotropic homogeneous turbulence and the planer channel flow. iDDES shows promising results to be used in future rocket combustion engine simulations and can make LES affordable in these kind of combustion simulations.
