Forced convective boiling experiments with HFE-7000 were conducted in earth gravity and under microgravity conditions. The experiment mainly consists in the study of a boiling flow (liquid-vapour flow) through a 6 mm diameter sapphire tube uniformly heated by an ITO coating. Measurements of pressure drops (on an adiabatic section), void fraction and wall and liquid temperatures are provided. High-speed movies of the flow are also taken. The data were collected in normal gravity and during a series of parabolic trajectories flown in an airplane. Flow visualizations, temperature, pressure and void fraction measurements are analysed to obtain flow pattern, heat transfer, film thickness and wall friction data.
