TWO-PHASE FLOW IN SPRAY COOLERS

Abstract

The problem of estimating pressure drops with typical in-line bar, spray cooler configurations is discussed. Such coolers form an important component of facilities for rocket testing at simulated altitudes. The complex nature of gas-liquid flows is first discussed. This is followed by a presentation of results of some simple experiments of air flow over a tube bank in a model spray-cooler section to determine the influence of this particular geometry on the drag coefficient. Based upon the information in these two sections, a semi-empirical analysis of two-phase flow in coolers is then developed and some results of the method are presented. Finally, recommendations are made concerning an experimental program which would enhance the further development of prediction techniques in cooler design.
