Heat pipe: A simple one-dimensional model and an experimental study

Research output: Contribution to journalConference articlepeer-review

Abstract

In this work the authors proposed to use 1-D model for heat and masstransfer calculations inside a porous heat pipe. Several limits are taken in to account: Sound, boiling, capillary and dry out of evaporator. To calculate the heat flow, we analyzed processes in four zones: The evaporator, the condenser, the porous body in which fluid flows, and the cavity in which steam flows. We assume that in the evaporator all the incoming liquid evaporates, and in the condenser, all the vapor condenses. The liquid and the vapor are in a state of saturation and, therefore, the pressure in the condenser and the evaporator is equal to the saturation pressure. The good agreement between theoretical and experimental results is observed.
