Abstract:
Pulsating heat pipes have been more studied in recent two decades as effective tools in dissipating waste heat from electronic components. Due to oscillating fluid flow model, these tubes have the potential of converting waste energy to power. This research presents a system that makes this potential to act. In this system, the oscillating slug-plug fluid flow pattern in an open-looped pulsating heat pipe makes a permanent magnet which is levitated in Ferrofluid to vibrate in an electromagnetic vibration-based generator in order to induce electro motive force. The fluid flow regime in pulsating heat pipe has been simulated numerically with finite element scheme. The model results for fluid flow used as input for magnetic field simulation and calculating power and induced voltage. By comparing the results of theoretical analysis and experimental data, the system performance is studied. Test results also determine the best operating conditions for the generator by the filling ratio and temperature difference between the hot and cold sources
