Abstract:

       We performed numerical simulation for the fluid flow and heat transfer process of plane and declined wave fin (15°, 30° and 45° declined angles) on oscillating heat pipe. We also obtained fluid temperature field and velocity field distribution and compared the results. Simulation results show that the heat transfer effect of declined wave fin on oscillating heat pipe increases with the increase of the declined angle, but pressure loss also increases. These simulation results are reference guide to heat transfer enhancement on oscillating heat pipe heat exchanger.

Key words: oscillating heat pipe, declined wave fin, heat transfer enhancement, numerical simulation
