Abstract
A study was conducted to determine the effects of varying the fluid properties of viscosity, surface tension, and density on liquid jet breakup, penetration, and spreading. Water, heptane, and a 58 per cent glycerin-42 per cent water mixture (by mass) were injected transversely into Mach 2.8 and 4.0 airstreams through various circular orifices located in the surface of a flat plate model. Experiments were performed with injector orifices varying in diameter from 0.0145 inches to 0.080 inches, using injectant total pressures ranging from 30 psia. to 3000 psia. Steady-state penetration and lateral spreading distances were measured from scattered light photographs, and qualitative analyses of shock waves induced by the liquid jet were made using schlieren photographs.
