Effect of Contact Angle Variation on Thermal Performance of Heat Pipe: Pore-Scale Numerical Simulation

EasyChair Preprint no. 10404

Abstract

In the present study, a pore-scale simulation approach is used to analyze the heat and mass transfer processes in the heat pipe. Due to its topographic structure almost similar to the sintered wick structure used in the heat pipes, Triply-Periodic-Minimal-Surface (TPMS) based Fisher-Koch lattice is used for geometrical modelling of the porous wick structure for the first time. A relatively smaller heat load of 1000 W/m2 is applied at the evaporator and condenser sections. Therefore, the effect of contact angle variation at solid-liquid-vapour interface is studied using the parameters like, temperature distribution, interface shape, and heat pipe limits (capillary, boiling, and entrainment), for heat transfer performance

Keyphrases: Heat pipe, Pore-scale simulation, TPMS lattice, two-phase flow
