This paper numerically investigated the self-oscillating mechanism of the vapor-liquid two-phase flow in 1-turn oscillating heat pipe. The phase change is simulated by using the temperature-recovery method which is combined with the VOF(Volume of Fluid) method. It is found that difference of bubble rate between left and right channel and average vertical flow velocity have positive correlation. Thus, the self-oscillating mechanism is related to the difference of bubble rate between left and right channel which is caused by phase change. Furthermore, heat transport performance of methanol shows higher than that of ethanol due to the higher latent heat.
