Based on Mixture and Euler model, numerical simulation was used to study the flow and heat transfer in pulsating heat pipe by unsteady method. By comparing the gas volume fraction and gas velocity by different models at different time, the results showed that both models could simulate the evaporation and condensation process of the working fluid, and the liquid plug and gas plug were formed in the tube. By comparing the gas volume fraction and gas velocity at 5s and 10s, it was indicated that the fluid dynamics and heat transfer were more violent by Mixture model in the tube.
