Modeling of internal melt ice-on-coil tank

Internal   melt   ice-on-coil   tank   with   built-in horizontal tubes is a kind of ice tank used widely. Its discharge process is effected greatly by density different between ice and water. The existing models developed for internal melt ice-on-coil tank are concentric cylinder models which are applicable to tank with built-in vertical tube or to case when all water in tank is frozen, but is not applicable to describing the effect of density difference between ice and water on discharge. This paper introduces an eccentric cylinder model developed especially for discharge process in this kind of tank with built-in horizontal tubes. The model has simple form and is suitable for system simulation. Experimental validation proved the reliability of the model.
