Time-dependent heat transfer simulation for NEPCM solidification inside a channel

Journal Article


Abstract


  • The aim of current investigation is to model NEPCM behavior in an air heat exchanger storage unit by means of FVM. Unsteady governing equations are obtained including single-phase model for NEPCM. Thermal properties of paraffin are enhanced with dispersing CuO nanoparticles. The geometry was symmetric, and so there is no need to simulate the whole domain. Converting liquid to solid makes the air flow warmer and helps the ventilation of building. Wavy wall was employed to accelerate the discharging rate. Outputs reveal that dispersing nanoparticles leads to propagation of solid front. Discharging rate enhances with augmenting amplitude of inner wall.
