Dynamic simulation of encapsulated ice stores. 2. Model development and validation.

Author(s) : ARNOLD D.

Summary

Part I of the paper (see 91-1820) analyzed the physical processes in encapsulated freezing and melting both at a micro level (within the capsule bed) and at a macro level (a portion of the store). In part II, laboratory measurements of the rate of heat transfer of encapsulated ice, published previously, are further analyzed and characterized such that they can be incorporated into the ice store model. The basic variation in heat transfer during phase change resulting from the increase or decrease in the thickness of ice in the capsule is represented by simple polynomial relationships. These relate the rate of heat transfer during freezing and melting to the ice fraction within the capsule. It is shown that a dynamic model can realistically simulate a complex heat transfer situation on a personal computer.
