This paper describes results of the thermal-hydraulic performance experiment of the two-phase flow loop using a sounding rocket which can maintain a gravity level of 10- 4 g0 for about six minutes. The feasibility study for this system had been conducted for loading into an experiment module of the sounding rocket. A flight model of the experiment system was designed and constructed in 1992. The experiment was successfully performed on September 17, 1993, and a thermal equilibrium of the flow loop could be obtained under microgravity. The flow pattern became the froth flow at the outlet of a cold plate, and isothermal condition in the cold plate was established by the two- phase flow operation. Details of the flow behavior, the heat transfer coefficient, and the pressure loss under microgravity are described.
