CAPILLARY PRIMING CHARACTERISTICS OF A HIGH CAPACITY DUAL PASSAGE HEAT PIPE

Abstract

A parametric study of the forces governing the liquid-vapor interface was performed for the purpose of determining the capillary priming characteristics of Grumman's dual passage monogroove heat pipe when subjected to low-g or zero-g conditions. The static liquid-vapor interface configuration was determined through the use of a mathematical model which utilized the technique of minimization of the free surface energies. A computer program which describes the lime to prime was then developed. Modeling predictions confirmed expectations or proper priming action and established the criteria for sizing of the liquid and vapor channels.
