SUMMARY:On wall-ice accretion or melting in shear flow - Frank Thomas Smit

DESCRIPTION:The interest here is in interactions involved in impacts\, ice
  formation and melting. There are many such interactions. This mathematica
 l-modelling research\, motivated originally by the observed icing of airbo
 rne vehicles and the effects of storms\, aims to address the following. Fi
 rst is the free motion of ice particles in air and water\, or the distorti
 on of water droplets in air flow\, where two-way fluid /body interactions 
 occur taking account of the small density and viscosity ratios. Second\, i
 ce growth soon after a droplet impact onto a fixed solid surface will be d
 iscussed\, where the interaction is between the ice shape and the water fl
 ow over it. Third\, related problems of melting or freezing of wall-mounte
 d ice in local shear flow will be considered\, concerning ice shards\, deb
 ris and /or lift-off from a solid surface.
