Experimental study in heat accumulators with a phase transition of matter

Abstract

The proposed article is devoted to the study of a heat accumulator with a phase transition of a substance, which is a model of an accumulator with a semi-co- occupational heat pipe through which a coolant (water) passes at different temperatures. To intensify the heat exchange process between the coolant and the heat-storing material, the tube is fitted with longitudinal and transverse ribs, and aluminum shavings are added to the HSM composition. The experimental results make it possible to suggest that there are such values of the studied parameters (flow rate, coolant temperature) at which a further increase in the latter does not have a significant effect on the rate of processes in heat accumulators based on a phase transition.
