A two-phase, non-thermal-equilibrium based model is applied to the numerical simulation of laminar flow and heat transfer characteristics of suspension with phase-change material (PCM) particles in a microchannel. This study focuses on the heat transfer enhancement effects for a very low Reynolds number (Re < 50) and high PCM concentration slurry flow (50−70%). With preliminary experimental confirmation in a minitube, simulation results show the existence of an optimal operating range for low Reynolds numbers and high PCM concentrations. It is also found that the particle viscosity value has a significant influence on the heat transfer enhancement effect of PCM suspension flow and a more realistic particle viscosity correlation is suggested.
