Author(s) : SHAH M. M.

Type of article: Article

Summary

THE TECHNIQUE IS BASED ON THE TWO-STEP MODEL AND CONSISTS OF A GRAPHIC CORRELATION FOR NONEQUILIBRIUM QUALITY AND AN EQUATION FOR LIQUID DROPLET COOLING AT HIGH PRESSURES. IT HAS BEEN DEVELOPED FROM AND VERIFIED WITH DATA FOR WATER, NITROGEN, PARA-HYDROGEN, R113, METHANE, AND PROPANE. THE RANGE OF DATA INCLUDES EQUILIBRIUM QUALITIES FROM 0.1 TO 2.9, PRESSURES FROM 1.4 TO 215 BAR, REDUCED PRESSURES FROM 0.01 TO 0.97, MASS FLUX FROM 30 TO 3,442 KG/M2.S, TUBE DIAMETERS FROM 2.5 TO 14.9 MM, HEAT FLUX FROM 0.012 TO 2.1 MW/M2, AND WALL TEMPERATURES FROM 81 TO 1,112 K. HEAT TRANSFER COEFFICIENTS BASED ON ACTUAL VAPOR TEMPERATURES ARE CORRELATED WITH A ROOT-MEAN-SQUARE ERROR OF 15%.
