Dynamics of Bubble and Drop in Multiphase Flow through Numerical Simulation

Abstract

An attempt is made to study the hydrodynamics of drop and bubble under various boundary conditions (including adiabatic and non-adiabatic boundary condition) using numerical simulations. The effect of various parameters like: drop diameter, Reynolds no., position of drop on the dynamics are studied. The numerical analysis of the drop and bubble is done using Finite Volume Method (FVM) with Volume of Fluid (VOF) model. At first, the kinetics of a drop on a horizontal solid surface under air flow (considering no heat transfer) is studied. Then the same problem with heat transfer through solid surface is considered. At last the hydrodynamics of a helium bubble through a vertical channel is studied. For each case the Reynolds number is varied for a considerable range.
