“…9(a) are the same for other simulation conditions, but the bubbles leave the heating surface under different gravity level conditions. According to the research of Zhao and Du et al [27,28] and their qualitative comparison with the RKM model, we choose the gravity levels as 0.08𝑔, 0.06𝑔, 0.04𝑔, 0.02𝑔, 0.01𝑔, 0.008𝑔, 0.006𝑔, and 0.004𝑔, respectively. It can be clearly seen from the shape of the bubble in the Fig.…”

In this paper, we use the phase field method to track the gas-liquid interface based on the gas-liquid two-phase flow in the pool boiling process, and study the bubble nucleation, growth, deformation, departure and other dynamic behaviors on the heating surface under microgravity. By simulating the correlation between liquid undercooling and bubble dynamics, we find that the bubble growth time increases with the increase of liquid undercooling, but the effect of liquid undercooling on bubble height is not significant. Meanwhile, the gas-liquid-solid three-phase contact angle and the gravity level will also have an effect on the bubble growth time and bubble height. With the increase of the contact angle, the bubble growth time and bubble height when the bubble is departure also increase. While the effect of gravity level is on the contrary, the smaller the gravity level is, the larger the bubble height and bubble growth time when the bubble separates.
