Experimental study on the convective heat transfer behavior of microencapsulated phase change material suspensions in rectangular tube of small aspect ratio

Research output: Contribution to journalArticlepeer-review

Abstract

An experimental study on the heat transfer performance of microencapsulated phase change material suspensions flowing in the rectangular tube of small aspect ratio (b/a = 0.14) is presented in this work. The slurry of higher MPCM concentration shows better cooling performance in the most section of dimensionless axial distance whereas worse in a small section at the beginning. Up to 20.6% of the dimensionless wall temperature was decreased by the 20 wt% MPCM suspension as compared to water.
