In this study, a new submodel concerning fuel film formation process is proposed in order to simulate the behavior of diesel spray impingement on relatively low temperature wall surface. Here, super - heating degree of the surface, defined by the temperature difference between the wall surface and the fuel saturated temperature, is newly considered for the behavior of impinged liquid droplets. In this spray impingement submodel, fuel film formation process, droplet interaction, film breakup process, and velocity and direction of dispersing droplets were considered based on several experimental results. This new submodel was incorporated into KIVA-II code, and the results were compared with experimental data KIVA-II original code and the spray / wall impingement model proposed by Naber & Reitz. As a result, it is found that the calculated results of impinging spray behavior by the new model agree well with experimental results.
