FLOW BOILING MAPS FOR WATER, R-22 AND R-134a IN THE SATURATED REGION
Résumé
The development of a flow boiling map applicable to different fluids was reported by Kandlikar (1989). In the present paper, specific maps are presented for water, R-22 and R-134a in the saturated boiling region to serve as a quick design reference for calculating the two-phase flow boiling heat transfer coefficient. The maps are drawn for three values of Во: 10−4, 5×10−4 and 10−3; and cover a pressure range of 1.01 to 75 bar for water and a temperature range of 10 to -18 °C for refrigerants R-22 and R-134a.
