Three Problems in Fluid Dynamics.

Abstract

Three problems were proposed for study. The first was to determine the fluid dynamics of spin-up of two fluids in a rotating container. The applications of these studies are the the problem of stabilization of rotating liquid-filled artillery shells in free flight and to the determination of the rheological properties of blends of polymers used to fabricate plastic composites with improved material properties. The second problem is to study the motion of solid particles in a flowing viscous fluid by direct numerical simulation of the Navier-Stokes equations and the particles equations of motion. The third problem was to identify correct physical mechanisms to regularize ill-posed problems which arise in the study of two-phase flows of bubbly mixture in spinoidal regions of phase change mixtures of vapour bubbles in liquids.
