Decomposition of a Liquid Jet Injected Normal to a Supersonic Air Stream,
Abstract
A systematic experimental study of the breakup of a liquid jet injected normal to a supersonic airstream was carried out. Included were the effect of liquid properties, jet flow rate, dynamic pressure ratio, Mach number (2.4 to 4.0), boundary layer thickness upstream of the jet, orifice size and shape, and level of jet back pressure relative to liquid vapor pressure. High-frequency, axially-propagating waves are studied as the principal decomposition mechanism, since in their instability they grow along the curved jet to a point where a large clump of fluid detaches from the cohesive jet at a wave-trough. The wave process was studied extensively by use of high-speed photographic techniques. (Author)
