Experimental Investigation of Water Ejection from a Wedge Model at Mach Number 6
Abstract
Tests were conducted at Mach number 6 to investigate the interaction between an ejected liquid (water) and a two-dimensional, zero pressure gradient boundary layer. Heat-transfer rates, static pressure levels, pitot pressure surveys, and photographic data were obtained on a 33.65-deg wedge model over a Reynolds number range, based on the distance to the ejector, from 260,000 to 3, 440,000. The water mass flow range was from 0.013 to 0.064 lbm/sec for both a porous panel and a slot-type ejector. Water ejection at 0.064 lbm/sec increased the boundary-layer thickness about 15 percent, and for all mass flow rates the model surface temperatures were equal to the water temperature (approx. = 75F). The primary data consisted of backlighted photographs of dyed water flowing over a glass plate on a wedge surface.
