Other AbstractIn order to develop space scientific experimental study of heat transfer law of the evaporation phase change and explore the influence of gravity on the evaporation and heat transfer process on the TZ-1 cargo spaceship, a set of experimental platform of ground evaporation is designed to study the evaporation phase change of FC-72 liquid. By using of infrared thermal imager, heat flux meter and differential thermocouple, the interface changes, evaporation surface characteristics, fluid properties, and Marangoni convection cell changes etc. are observed, of FC-72 liquid layer under different temperature and volume of liquid injection. Then the liquid layer temperature difference, surface temperature field, heat flux value, evaporation rate and convection cell structure of the two phase fluid are obtained. The experiment results show that the evaporation rate is proportional to the temperature difference between the FC-72 layer and the evaporation platform surface. And the evaporation rate is also proportional to the volume of liquid injection. In addition, buoyancy convection cells and Marangoni convection cells emerge in the evaporation process. These results are of important guiding significance for space scientific experiments. The experimental medium and material of space experiment can be decided according to the results of ground evaporation experiments. Consequently, the operating conditions, parameters, and procedure of space experiment can be optimized. Part of the ground experiment results will directly act as the scientific achievements of the ground and space comparison experiments.
