摘要：

Probabilistic two-phase flow map data is experimentally obtained for R134a at 25.0, 35.0, and 49.7 degrees C, R410A at 25.0 degrees C, mass fluxes from 100 to 600 kg/m(2)-s, qualities from 0 to1 in 8.00, 5.43, 3.90, and 1.74 mm I.D. single, smooth, adiabatic, horizontal tubes in order to extend probabilistic two-phase flow map modeling techniques to single tubes. A new web camera based flow visualization technique utilizing an illuminated diffuse striped background was used to enhance images, detect fine films, and aid in the automated image recognition process developed in the present study. This technique has an average time fraction classification error of less than 0.01.
