Modeling and Validation of the Ice Growth in an Ice Storage System

Abstract

This work deals with the optimization of the icing process in an ice storage system. It is focused on the improvement of the icing behavior, which is to be achieved by different heat exchanger geometries in the ice storage tank. Therefore, CFD simulations were implemented to acquire and visualize the flow conditions, the temperature behavior and the growth of the ice layer during the cooling process. The results are compared and validated with model experiments on an experimental ice storage. It could be shown that the heat extraction of current technologies can be increased by more than 50% by using geometries that are more efficient.
