Impacts, ice growth and related modelling

Presented by: 
Frank Thomas Smith University College London
Thursday 9th November 2017 - 09:00 to 10:00
INI Seminar Room 1
The presentation here by Frank Smith and Davide Bella is on interactions involved in impacts, ice formation and related phenomena. There are many such interactions. This mathematical-modelling research, motivated originally by the observed icing of airborne vehicles and the effects of storms, aims to address some of the following issues: first, distortion of water droplets in air flow, where two-way fluid interactions occur taking account of the small density and viscosity ratios; second, air-water interaction during the impact of a droplet onto a solid surface, including pre impact and post impact behaviour; third, ice growth soon after impact, where the interaction is between the ice shape and the water flow over it; fourth, related problems of dynamic fluid-body interaction concerning ice lumps impacting on a solid surface. More basic study of the ice growth within a single droplet on a solid surface will also be presented.
