Analysis and Computation of Viscous Flows: 3D Flows, Separation and Transition

Abstract

A triple-deck theory was developed for thermo-mechanical interaction of air, ice and water. A novel interaction regime was found in which the low speed lower - deck flow can interact with both the liquid - film/droplets and the ice growth through a Stephan condition. A new broad band icing instability was observed, which is believed can lead to the creation of complex short scale roughness and provide a mechanism to explain the sensitive dependence on initial conditions often observed in icing experiments.
