Analysis of a High-Heat-Flux Water Heat Pipe Evaporator.

Abstract

An analysis was made to determine a surface which has potential use in a high-heat-flux, low-temperature-drop water heat pipe evaporator. Two groove geometries were selected for analysis, rectangular and triangular. A mathematical model of the grooves was constructed in order to predict the maximum surface heat flux capability. In addition, a model of the heat transfer within the fluted surface was proposed which postulated that conduction through the wall and liquid to the liquid-vapor interface is the mechanism of heat transfer. A numerical analysis of the heat transfer in the groove was made based on the proposed model to predict evaporator film coefficients. The numerical heat transfer models were two-dimensional which used average meniscus profiles obtained from simpler, three-dimensional models. (Modified author abstract)
