Abstract:
Pulsating heat pipe is an efficient heat exchange device which is being used for cooling and heating recovery .In the present work, we made a closed-loop pulsating heat pipe with six U-turns and we used water in our system with 40% and 50% filling ratios. Moreover, the use of water-Fe3O4 nanofluid was studied with two different filling ratios 40% and 50% and 1% mass concentration. Then, we used several magnets to produce 100 G magnetic field. At the end, we calculated heat resistance and heat transfer coefficients of water and water-Fe3O4 nanofluid in each step and compared the results and showed that 50% filling ratio of water-Fe3O4 nanofluid with magnetic field was the best choice in our study because of the best heat transfer coefficient.
