Conjugate Unsteady Heat Transfer from a Spherical Droplet at Low Reynolds Numbers

Abstract

The energy equations governing the heat transfer from a spherical droplet moving in a continuous medium are solved numerically using an implicit ADI type finite difference method. The numerical solutions give the nondimensional temperature profiles from which the bulk temperature and the Nusselt numbers are calculated. Different values of thermal properties can be considered for the two phases. The fluid velocities are assumed to be known. The numerical procedure given here eliminates certain spurious oscillations and other difficulties encountered in earlier studies.
