Abstract
Round jets are computed using large-eddy
simulations based on low-dissipation schemes to investigate the influence of initial
conditions on their self-similarity regions. Three jets with the same initial parameters
except for the diameters yielding Reynolds numbers of 11000, 3600 and 1800 are first
considered, then two additional jets at Reynolds number 3600 but with modified initial
shear-layer thickness and forcing are calculated. The properties of the mean and
turbulent flows are compared
