An Annular Flow Ice-Water Model Heat Sink.

Abstract

An analytical and laboratory experimental study was conducted on a scale model annular flow ice-water heat sink which represent a medium for storing waste heat developed by a hardened defense installation during a transient period in which it operates on a closed cycle system. The study developed (1) an understanding of the flow processes and melting patterns in such a sink, (2) a mathematical procedure for predicting relationships between coolant water and heat rejection rates, (3) a validation of the math procedure using a scaled experiment model, and (4) an assessment of the effect of some water inlet manifold configurations. Advantageous performance characteristics include provision for (1) maximum thermal efficiency during the early (probably most crucial) stages of use and (2) a relatively constant outlet sink temperature to the power plant heat exchanger during the ice melting period.
