Experimental Investigation of Ten Turn Closed Loop Pulsating Heat Pipe Thermal Performance and Validation Using CFD Simulation of Single Turn
Thermal management is the challenge of the day in electronic product development. Compact electronic devices produce excess heat and rejection of this heat is necessary for their reliable performance. Closed loop pulsating heat pipe has a great prospect in the upcoming days for an effective cooling solution due to its excellent heat transfer characteristics. In this paper the closed loop pulsating heat pipe (CLPHP) setup of 2 mm internal diameter and ten turn was prepared in vertical bottom heat mode. Experiments were conducted with DI-water as working fluid for different heat loads as 20 W, 40 W, 80 W and 120 W. Thermal performances was studied and CFD simulation was carried out to compare experimental results. The ANSYS Fluent 17.0 software used to simulate CLPHP performance. VOF model was selected in Fluent 17.0 to analyze phase change process and surface tension effect considered under the surface force model. The simulation was carried out for only single turn to validate the results with experiments. The CFD simulation in Fluent 17.0 was successful in reproducing the two phase flow process in CLPHP. The bubble generation in evaporator section and oscillation in CLPHP was successfully simulated by the ANSYS Fluent 17.0 software. The comparison of results for same operating conditions between experimental and CFD simulation of CLPHP were carried out.
