Abstract
Large-eddy simulations are performed using low-dissipation numerical schemes combined with a relaxation filtering as subgrid dissipation to investigate the influence of the Reynolds number and the grid resolution on self-similar turbulent circular jets. Three jets with the same initial parameters except for the diameters yielding Reynolds numbers of 1800, 3600 and 11000 are first considered. Then two additional jets at Reynolds number 3600 are calculated using coarser grids in the turbulent flow regions. Energy dissipation and filtering activity are examined in the different simulations, and mean and turbulent properties of the jets are compared.
