Summary

AN EXPERIMENTAL STUDY IS PRESENTED CONCERNING THE SATURATED AND SUBCOOLED BOILING OF WATER AND R113 AT ATMOSPHERIC PRESSURE ON CHEMICALLY ETCHED SURFACES. IT IS SHOWN THAT THE CHEMICAL ETCHING HAS A REMARKABLE INFLUENCE ON BOILING. SPECIFICALLY, IT CAUSES A LARGE INCREASE OF THE ACTIVE SITE DENSITY FOR A GIVEN SUPERHEAT OR HEAT FLUX, BOTH FOR SATURATED AND SUBCOOLED BOILING; ALSO THE BUBBLE FREQUENCY IS MARKEDLY INCREASED BY THE ETCHING, WHILE THE MAXIMUM DIAMETER IS NEGLIGIBLY INFLUENCED. COMPARISON OF THE EXPERIMENTAL RESULTS WITH THEORETICAL AND EMPIRICAL CORRELATION IS REPORTED AND DISCUSSED.
