Grooved heat pipes are critical passive heat transfer devices widely employed in heat transfer and electronics cooling applications due to their superior reliability and capability of transferring high heat loads with small temperature differences. However, the analysis and design of grooved heat pipes may be challenging due to phase change and free surface, two-phase flow, and heat transfer. Our research group has recently developed a mathematical model for pseudo-3D analysis of grooved heat pipes under different operating conditions, which was named as Heat Pipe Analysis Toolbox (H-PAT). Currently, our mathematical model ignores the effect of the vapor flow within the heat pipe and does not take into account the pressure drops on the vapor side. If the vapor space is large, the viscous effects on the vapor side and at the interface may be safely neglected. However, the effect of vapor flow may be quite significant for heat pipes that have a confined region for vapor flow. In this case, the pressure drops on the vapor side and the viscous effects at the interface need to be included. In this study, our mathematical model has been extended to compute the liquid and vapor flows at a given cross-section by solving Poisson’s equation with the appropriate boundary conditions via COMSOL Multiphysics.
