Analysis of Influence Factors on the Internal-Melt Ice-on-Tube while Melting

Abstract:

The numerical simulation is widely used in study of the ice storage system. The model about melting is established and solved by using enthalpy method. Natural convection of the melted water in the course of melting is studied. Effects on the performance of heat-exchange, caused by variation of velocity of the refrigerant, inner diameter of the tube, initial temperature of the external water and inlet temperature of the refrigerant, are simulated and analyzed. 1. As the increase of cryogen inlet temperature, the influence of natural convention is more and more in the process of melting heat transfer. 2. Under the conditions of the different cryogen velocity, the different diameter of tube and the different initial temperature of ice layer, the effect of natural convention also is different in the process of melting heat transfer.
