A study is reported of boiling heat transfer with saturated liquid nitrogen under atmospheric pressure at standard, fractional, and near-zero gravity. A drop-tower technique is used to achieve the reduced gravities. Because of the short test time available a transient technique using a sphere as a transient calorimeter is employed to obtain the heat-transfer data. This technique permits the ready acquisition of data in all boiling regimes from the film boiling region through nucleate boiling. Comparison is made with correlations for film boiling and for maximum and minimum heat flux and their corresponding Δtsat.

Qualitative Effect

A photographic study was made to determine the qualitative effect of zero gravity on the mechanism of boiling heat transfer. The experimental equipment included a container for boiling water and a high-speed motion-picture camera. To eliminate the influence of gravity, these were mounted on a platform which was allowed to fall freely approximately 8 ft. During the free fall, photographs were taken of boiling from various surface configurations such as electrically heated horizontal and vertical ribbons. The heat flux was varied to produce conditions from moderate nucleate boiling to burnout. The results indicate that gravity plays a considerable role in the boiling process, especially in connection with the motion of vapor within the liquid.
