The aim of this Faraday Partnership project was to develop models of high speed impact of water droplets, into water layers, that result in splashing. Heat, as well as mass, transfer will be included, and the effects on surface geometry will be carefully studied. This research enhances the understanding of ice formation on aircraft passing through clouds.
The basic splashes and rebounds proposed for study are provoked by an incoming water droplet, with or without angle of incidence, impinging on an otherwise still layer of water. In addition to this pure impact at incidence the research incorporated the influences of pre-existing air and water flow, for example with high shear, air cushioning and related factors. New theory and modelling from first principles and closely allied computations are required for the droplet and impact dynamics.

This project was carried out at University College, London, in conjunction with QinetiQ, Farnborough. It was supported by earmarked EPSRC research funding, through the Faraday Partnership for Industrial Mathematics, and has the working title Droplet impact on water layeres. Start date: October 2002; Duration: 2 years.
