通过对微重力和重力场下流场特点的比较，基于动量力，从地面上模拟微重力下的两相流动和受迫核态沸腾换热两方面出发，提出了地面上模拟微重力下两相流动沸腾换热的可行性条件：竖直试验段两相流速必须超过某一极限，试验段出口的气相含量也必须满足一定的要求．这些为该试验的开展奠定了初步的理论基础．
Based on the comparison of the characteristics of the flow field under the microgravity and the gravitational field, two-phase flow and forced nucleate boiling heat transfer under the microgravity are simulated on the ground based on the momentum, Phase flow boiling heat transfer feasibility conditions: vertical test two-phase flow rate must exceed a certain limit, the experimental section of the gas content of the outlet must also meet certain requirements. These laid the initial theoretical foundation for the experiment.
