Abstract

An extension of the OPT model is proposed, which can predict the breakup processes of liquid droplets on walls having various affinities. It should be emphasized that, while Weber numbers and wall characteristics are varied, the mass remained on wall is predicted after wall-impingement. Nonlinearity in the model is important for predicting the phenomena. The present breakup model can be used as a sub-model for multi-dimensional numerical codes including sprays and air flows, because of simple ordinary differential equations.
