Abstract

The aim of this paper is to present approaches undertaken in analysing the thermal performance of a cylindrical heat pipe with copper-sintered wick. The approaches employed are the thermal resistance network, the lumped capacitance method (LCM) and two-dimensional numerical CFD simulation. The predicted variation of the evaporator temperature with different heat inputs were compared against experimental data. The accuracy of the prediction was also determined by finding the percentage difference of the calculated results with that from the experiments. All methods have shown to produce results that are in good agreement with the experimental works. The best method is the LCM, giving predictions that deviate from experimental data by as much as 3.9%, followed by the thermal resistance network and the numerical simulation with maximum percentage differences of 4.6 and 9.8%, respectively.
