Experimental and numerical investigation of 2-dimensional heat pipe wall temperature profile

Abstract

This study focuses on the numerical validation of a two-dimensional model of a heat pipe's temperature profile under transient conditions. The model was constructed from copper, and the finite difference method was employed as the numerical solver. The study recorded the temperature distribution at the pipe wall in the evaporator, adiabatic and condenser sections, with a focus on the initial temperatures of the evaporator section. The temperatures at the pipe wall were compared with the numerical computation solutions. The results showed an agreement between the experimental and numerical temperature profiles with percentage error between 4.463 and 5.900 %.
