Influence of the location of the phase-change material on heating and cooling the heat-insulating layer

Abstract

The experimental investigation of thermal parameters during heating and cooling of PCM sample placed at different locations has revealed that the phase transition was accompanied by a significant decrease in the growth rate of the PCM temperature when heating, and a slowdown when cooling. The completion of the phase transition upon heating the PCM sample was accompanied by a sharp increase in the heat flux density at the outer surface of the PCM regardless of its location. The produced experimental results on the change of thermal parameters of the PCM depending on its location will be used to verify the calculation model.
