Abstract

•A synthetic boundary condition for turbulence has been successfully implemented in the open source code DNS Paris-Simulator. •Once implemented, the spray primary atomization process has been simulated for three cases with different levels of turbulence, quantified by the lengthscale and the turbulence intensity. •Results from the simulations have been compared in terms of vorticity field, external non-perturbed length and intact core length which are directly related to the atomization level. •Results reflect that atomization is greatly improved when the turbulence intensity and turbulence lengthscale are increased. •The different atomization processes, occurring in different spray locations have been analyzed.
