Abstract
read moreAn experimental investigation was conducted in a 3.84- by 10-inch tunnel to determine the mass transfer by sublimation, heat transfer, and skin friction for an iced surface on a flat plate for Mach numbers of 0.4, 0.6, and 0.8 and pressure altitudes to 30,000 feet. Measurements of rates of sublimation were also made for a Mach number of 1.3 at a pressure altitude of 30,000 feet.
The results show that the parameters of sublimation and heat transfer were 40 to 50 percent greater for an iced surface than was the bare- plate heat-transfer parameter. For iced surfaces of equivalent roughness, the ratio of sublimation …
