Laminar forced convection heat transfer with phase change material suspensions

This paper presents results related to laminar forced convection heat transfer to a phase change material suspension in a circular duct with constant wall heat flux. An effective specific heat approach has been used to model the heat transfer process for a flow with a fully developed velocity profile. The model has been verified by comparing its numerical predictions with previous theoretical results as well as well as experimental data. A simple correlation for wall temperature rise as a function of the tube length that can be used for future design has been developed based on a parametric study.
