Abstract
Improvement of computational methods for predicting the flow of droplets impingement in various industrial applications are hoped. In particular, in order to deal with industrial problems, a numerical scheme should be capable of easily deal with complicated interface topology change such as coalescence, breakup and so on. In the present paper, we investigate the possibility of DIM (diffuse interface model) as an interface tracking method to well respond to the topological change of interface. A problem of a single droplet impingement is examined to validate the performance of the DIM. Further multiple droplets impingement are investigated.
