Résumé

A novel method of dynamic ice forming, liquid-liquid circulating fluidized bed, was studied by using direct contact heat transfer between drops and the coolant for ice storage system. In order to simulate the multiphase flows and heat transfer in circulating fluidized bed, a numerical model was developed. Energy discharge was discussed for liquid-liquid circulating fluidized bed based on the second law of thermodynamics. Numerical method was used to study the influence of operating parameters, such as the droplet diameter and the inlet temperature or velocity average of liquid phase, on the ice-making performance and total energy discharge in the dynamic ice-making process. The research results indicate that ice-making performance always increases with decreasing droplet diameter and the inlet temperature of liquid phase and not so much with decreasing the inlet temperature of liquid phase. Moreover, decreasing the droplet diameter is considered to be the best way with consideration of the contradiction of ice-making performance and energy discharge.
