Numerical Simulation on Finned Heat Pipe under the Condition of Convection

Abstract:

This paper intends to use Gambit software to set up different mathematical models for the finned heat pipe, separately from the perspectives of three-dimensional, steady-state, natural and mixed convection. And then, it also uses Fluent software to do numerical simulation on the influence of different fin spacing, fin height and fin angle under the conditions of natural convection and different horizontal wind speed on heat transfer performance of fin under the conditions of mixed convection. The results show that, under the condition of natural convection, increasing the fin spacing, fin height and fin angle with the horizontal angle can improve the heat transfer performance of finned heat pipe; Under the condition of mixed convection, with the increase of horizontal wind speed, on which the horizontal wind speed has a greater influence, the heat transfer rate and heat transfer coefficient of fin present approximately linear increase.
