Modeling of diesel spray impinging on flat wall

Abstract

We present a new model of the dispersion process of nonevaporating and evaporating diesel sprays impinging on a flat wall. The models concerning 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 sprays. They were incorporated into KIVA original code. The calculated results obtained using the new models show good qualitative correspondence with the experimental results, compared with those obtained using KIVA original code.
