文摘

Experimental results of the dynamic melting enhancement technique is presented. Dynamic melting enhanced the heat transfer during the melting process. Enhancement was obtained when the PCM flow rate is higher than the HTF flow rate. Pumping power was shown to be negligible relative to the heat transfer enhancement. Heat gains from the surroundings have influenced the system performance.
