Title

A Fluid Management System For A Multiple Nozzle Array Spray Cooler

Abstract

An experimental investigation of a fluid management system for a multiple nozzle spray cooler array was conducted. A fluid management or suction system was used to control the liquid film layer thickness needed for maximum heat transfer. An array of sixteen pressure atomized spray nozzle along with an imbedded fluid suction were constructed. Two surfaces were spray tested one being a clear grooved Plexiglas plate used for visualization and the other being a bottom heated grooved 4.5 × 4.5 cm2 copper plate used to determine the heat flux. The suction system utilized an array of thin copper tubes of outer diameter 3.175 mm to extract excess liquid from the cooled surface. Pure water was ejected from two spray nozzle configurations at flow rates of 0.7 L/min to 1 L/min per nozzle. It was found that the fluid management system provided fluid removal maximum efficiencies of 98% with a 4-nozzle array, and 90% with the full 16-nozzle array for the downward spraying orientation. The corresponding heat fluxes for the multiple spray head configuration were found with and without the aid of the fluid management system. It was found that the fluid management system increased heat fluxes on the average of 30 W/cm2 at similar values of superheat. © 2004 by the American Institute of Aeronautics and Astronautics, Inc.
