Abstract: Heat pipes are drawing attention due to higher heat transfer capabilities in various applications such as electronic cooling, nuclear reactors cooling, solar collectors etc. In the present work, a heat pipe is considered for cooling of electronic components utilized in industrial applications. A computational geometry of heat pipe is developed in ANSYS®, a commercial software package, and meshed uniformly. This meshed geometry is exported to ANSYS-FLUENT for investigation on the evaporation and condensation phenomenon due to mixed heat transfer. It is observed that relatively non uniform temperature distribution prevails in the heat pipe. It is seen that FLUENT with the Volume of Fluid (VOF) method can effectively model the complex phase change phenomena of the heat pipe. |
Keywords and phrases: multi-phase flow, evaporation, condensation, transient.
