Abstract

"Void fractions were determined experimentally for Refrigerants 134a and 410A condensing inside a smooth horizontal 7.04 mm (0.277"") i.d. tube. Tests that encompass a range of mass fluxes from 75-450 kg/m2-s (55-330 klbm/ft2-hr) and inlet qualities of 0.13- 0.9 were performed at a temperature of 35°C (95 OF). The experimental apparatus and procedures are described. The predictions of several existing correlations deviate from the experimental data, which necessitates the formulation of a new void fraction correlation. The correlation presented here is in terms of a Froude rate parameter, and accurately predicts the experimental data."
