摘要 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． By comparing the characteristic of the flow field under normal gravity with that under microgravity and with a consideration for carrying out under normal gravity the simulation of two-phase flow and forced nucleate boiling heat transfer under microgravity, based on the momentum force, the feasibility conditions for the simulation under normal gravity of two-phase flow boiling heat transfer under microgravity are put forward. The two-phase velocity in the vertical experimental section must exceed a certain limit and the vapor content at the outlet of the testing tube must also meet a certain requirement.
