Abstract

Analytic and numerical methods are applied to describe heat conduction in a PCM shell coupled to fluid flow forced convection in a coaxial inner tube. The analytic solutions rely on small Stefan and Stanton number approximation. The numerical solutions, derived within the weak formulation, allow to relax these assumptions and to consider both turbulent and laminar flows of the heat transfer fluid. 1 Introduction Latent heat thermal storage in a solid-liquid phase change has been proved an interesting way to stabilize the operation of a solar dynamic power plant [1,2]. A typical Latent Heat Thermal Sto
