Abstract
Void fractions were detennined for Refrigerants l34a and 4l0A evaporating inside three different tubes during horizontal flow. These tubes are as follows: a smooth 4.26 mm i.d. tube, a 7.25 mm axially grooved tube, and a 7.26 mm 18° helically grooved tube. Tests that encompass a range of mass fluxes of 75 - 700 k~, inlet qualities of 0.10 - ms kW 0.80, and heat fluxes of 0 - 10 -2 were performed at a temperature of 5° C. The m experimental apparatus and procedures are described. The predictions of several existing correlations are compared to the data, and recommendations as to which correlations are best suited for particular applications are given. Also, adjustments to these correlations are recommended for special geometries, and for simplicity of use.
