    Abstract
  • TZ-1 ground matching experiment is important to optimize the space science experiment parameters and technical parameters of two-phase test system. The correctional data for space experiment can be provided through scientific matching condensation experiments on the ground by observation of the influence of condensation experiment condition change on the unsteady condensing. The experiment mainly includes:changing condensing units and steam temperature, to obtain the rule of temporal change so as to guide the space experiment data acquisition and liquid pool heating; validating the influence of steam pressure on the liquid film heat transfer coefficient. Through a series of experiments, it can be seen that the condensation temperature, vapor temperature, extraction pressure also have great impact on the heat exchange coefficient, and at the same time, TZ-1 ground matching experiment has high guiding significance to improve the experiment device, optimize the condition and experimental parameters and improve the reliability.
