Title: Modelling fluid /body interactions

Speaker: Frank Smith, University College London

Abstract:

The interest here is in free motion of a body (particle) within fluid flow concerned with impacts and ice formation. Many interactions are involved. This mathematical-modelling research, motivated by observed icing of vehicles and by environmental and biomedical applications, aims to address several related problem areas. One area is the two-way fluid /body interaction occurring when a body is lifted off the ground by an oncoming fluid flow, with account taken of the small density and viscosity ratios present. Another area is on the impact of a body, passing through air, onto a solid surface. The effect of a water layer here is also of relevance. 

Biography:

Frank Smith is a Professor at University College London who was selected as a fellow of the Royal Society in 1984. He is a fluid dynamist and applied mathematician with particular interests in boundary-layer theory and hydrodynamic modelling. Professor Smith is a world-renowned expert on the boundary layer — the layer of liquid in the immediate vicinity of a surface — and his findings have revealed how fluids flow around objects with rough boundaries or transition from one type of flow to another. His research has applications in biomedicine and important implications for aviation safety.
