Ice-water two-phase flow behavior in ice heat storage systems

In this paper, we describe (1) the characteristics of ice-water two-phase f low created in a supercooling-type ice storage system, (2) the numerical an alysis models for both processes of ice storing and melting within ice stor age tanks, and (3) the design technologies for ice storage systems based on such predictive models, as well as the operational performance of actual e quipment built with these design technologies. As the result of this techno logical development, it has been confirmed that the predictive approaches f or the one dimensional ice accumulation in the given tanks and ice melting with low temperature water enough to air conditioning applications are reas onable and widely usable. Furthermore by the design conditions obtained her e it is possible to simplify the construction of ice storage tanks and to r ealize high reliability in the actual equipment.
