Subcooled, critical heat-flux test data on refrigerant R-11 flowing vertically in a uniformly heated circular tube is reported. Using the data reported by Coeffield for R-113, a method is presented for obtaining a direct heat-flux scaling factor between refrigerant and water with the same geometry, mass velocity, and local flowing quality when the pressure is adjusted so that the liquid-to-vapor density ratios are equal in both systems.
