ENHANCEMENT OF HEAT TRANSFER USING PHASE CHANGE MATERIAL WITH WATER MIXTURE

The present study deals with the Convective heat transfer performance of Phase Change Material (PCM)/Water mixture less than 0.4% volume concentration were tested using double pipe circular tube heat exchanger. We choose Erythritol as a phase change material, it has robust effect of cooling or optimistic heat of solution and latent heat of fusion is nearly equal to ice. The result shows that the addition of small amount of Erythritol powder to the base fluid water enhance the heat transfer coefficient considerably. The enhancement was about average of 2.3% increase in heat transfer coefficient was observed with 0.1% volume of PCM/Water mixture and average of 50.3% increase in heat transfer coefficient was observed with 0.3% volume of PCM/Water mixture.
