Experimental Scaling Study of an Annular Flow Ice-Water Heat Sink,
Abstract
A laboratory experimental study was conducted on a scale model of an annular flow ice-water heat sink to be used to store the waste heat produced in a hardened defense installation operating in an isolated mode. The study examined: (1) scaling relationships for predicting the performance of prototype units using data from scale models, (2) the accuracy of a computer prediction technique developed during an earlier study, (3) the heat transfer phenomenon at the ice-water interface, and (4) some practical aspects related to the operation of a prototype installation. The scaling relationships and the computer program were found to be sufficiently accurate for use in developing a prototype sink design. During operation the scale model sink provided an almost constant low temperature source of coolant water for approximately one-half its useful life and thereafter behaved like an ordinary stored water reservoir type heat sink. No significant operational problems were discovered. (Author)
