The physics of the atomization process involves many complex phenomena, which occur at different scales of space and time. The numerical study of such a problem is a great challenge for different reasons. Large density ratios, presence of a singular surface tension force, interface localization and transport, mass conservation, all of these make accurate numerical simulation difficult to perform. Several strategies have been investigated at ONERA in order to find an optimal method to simulate the atomization process with the CEDRE code. Both interface capturing and diffuse interface algorithms have been tested. The present development consists in the implementation of a multi-fluid version of the current gas solver of CEDRE, which conserves all its original features. One of the principal axes of research is based on a method which couples the new multi-fluid method with one of the dispersed phase solvers of CEDRE. The long term purpose is to be able to perform numerical simulation of both primary and secondary atomization.
