Nucleate boiling of oxygen under reduced gravity

Experimental results are presented on the coefficients of nucleate boiling heat transfer of oxygen under the conditions of low loading factors at elevated pressures. Based on the statistical distribution of the separation bubble radii and distances between the nucleation sites, a relation is obtained which provides a satisfactory description of the function α(q) in case of deteriorated heat transfer at eta = g/g/sub n/ < 0.1
