Nonlinear two-phase flow-surface interactions

摘要

The papers contained in this section represent a wide diversity of studies that are being undertaken relating to nonlinear behavior for various types of two-phase situations that involve interfacial surfaces.They range from highly practical applications like the paper by Warrier and Witte,in which they use the hyperbolic form of the heat equation to gain information about liquid-solid contact during flow film boiling.The paper by Cox and Yao also represents a practical problem of determining the impact of large water drops on a hot surface,Nelson and Bejan present an alternative way of thinking about how convective flows organize themselves according to "constructal theory".Optimization of shapes that result from this theory reveal most of the characteristics of convective flow,including nucleate boiling.Linker and Razani's paper contains a different approach to determining the effects of heat transfer augmentation by using a fluid "particle" that periodically contacts the solid surface.The paper by Winterton and Munaweera adds new data to our knowledge of bubble size distributions in two-phase bubbly flows.Such information is needed to apply two fluid models of heat,mass and momentum exchange in two-phase flows.Finally,Matumota uses the relatively new science of molecular dynamics to model the behavior near the contact line of droplets on a surface.
