The heat transfer characteristics of solid-liquid phase change material (PCM) suspensions in a rectangular natural circulation loop was investigated. A continuum mixture flow model was used for the buoyancy-driven circulation flow of the PCM suspensions together with an approximate enthalpy model to describe the solid-liquid phase change process of the PC particles. Numerical simulations through finite difference method were conducted for the pertinent physical parameters of a loop with fixed geometrical configuration. The results show that the melting/freezing processes of the PCM particles at the heated/cooled sections of the loop are closely interrelated in their conditions of the suspension.
