Author(s) : KLIMENKO V. V.

Type of article: Article

Summary

A CORRELATION FOR FORCED CONVECTION VAPORIZATION HEAT TRANSFER IS SUGGESTED WHICH IS VALID FOR BOTH VERTICALAND HORIZONTAL CHANNELS WITH A FULLY WETTED PERIMETER. IT REPRESENTS, WITH A MEAN ABSOLUTE DEVIATION OF 12.9%, EXPERIMENTAL DATA FOR WATER, CFCS AND CRYOGENS IN THE FOLLOWING PARAMETER RANGES: PRESSURE 0.061-3.04 MEGAPASCALS, MASS FLOW RATE 50-2,690 KG/M2 SEC, VAPOUR QUALITY 0.017-1.00, CHANNEL DIAMETERS 1.63-41.3 MILLIMETERS. THE VAPORIZATION HEAT TRANSFER RATE IS FOUND TO DEPEND ON THE THERMAL CONDUCTIVITY OF CHANNEL WALL MATERIAL. A UNIVERSAL CRITERION FOR CONVECTIVE BOILING IS SUGGESTED.
