Abstract

This paper is concerned with a novel procedure for calculating fluid flows in geometries with a time-dependent boundary and its application to a liquid drop problem. The procedure, which employs the SIMPLE algorithm as the solver, can incorporate a multi-block iteration with a moving mesh arrangement in the numerical modelling. For the liquid drop problem, the fluids flows inside and around the interface of the drop are studied numerically. To examine the robustness of the calculating procedure, three cases for different density and viscosity ratios are calculated; two types of returning wake vortex are observed. On this basis, a liquid drop in an industrial process of liquid spraying is studied. The structure of the wake vortex and its variation with exterior Reynolds number of a spherical drop are simulated.
