AN ANALYSIS OF PHASE CHANGE HEAT TRANSFER IN A SOLAR THERMAL ENERGY STORE

In this paper, a numerical analysis of heat transfer in the latent heat store has been performed. Heat transfer in the latent heat store is the conjugate problem of the phase change of the phase change material and the transient forced convection between the heat transfer fluid and the wall. The differential equations of flow and heat transfer, with initial and boundary conditions, have been discretized by control volume approach and then solved using an iterative procedure. The set of algebraic equations has been solved by FORTRAN software. Velocity and temperature distributions of heat transfer fluid as well as temperature distributions of the wall and PCM inside the latent heat store have been obtained.
