The objective of this study was the investigation on the dispersion process of non-evaporating and evaporating diesel sprays impinging on a flat wall. In the former case, the wall temperature T_w was less than the saturated temperature T_<sat> of the fuel. In the latter case, T_w was greater than T_<sat>. New models concerning the fuel film formation on the wall and its breakup process due to the droplet impingement, the breakup of an impinging droplet owing to boiling at the liquid-solid interface and the heat transfer from the wall to a droplet were constructed for both temperature conditions. These models were incorporated into KIVA original code. Then, calculated results were compared with the experimental results. The calculated result by new models has good qualitative correspondence with the experimental one, compared with that by KIVA original code.
