Simulation Study of Enhanced Phase Change Thermal Storage in Parabolic Trough Evacuated Tube Solar Collectors
To enhance the thermal conductivity of phase change material in parabolic trough evacuated tube solar collectors,a novel design combining a phase change material embedded metallic foam and a semicircular tube enhanced heat transfer structure was developed.FLUENT software was utilized to numerically simulate the heat transfer during the heat storage process.The study focused on the im-pact of integrating fins and metallic foam into the phase change material under non-uniform heat flux density distribution on the liquid fraction of the phase change material.
