Book Description
The paper reports a study of normal and lateral spray penetration for small diameter, high pressure, liquid jets issuing at an angle to a uniform supersonic stream. The experimental program described was carried out in a 4-in. by 4-in. blow down supersonic wind tunnel. The flow field is observed by means of a schlieren system, and the spray distribution is indicated by the light scattered by the liquid droplets. The data on normal penetration, in good agreement with data inferred from other investigations, indicate that a single-parameter correlation exists between the properly nondimensionalized penetration height and the injection pressure ratio. Injecting the coolant at a forward angle to the flow produces no substantial change in the penetration height. The data on lateral penetration show the spray width behind the jet to be proportional to the jet diameter with only a weak dependence on the injection pressure ratio. Analytical models proposed by previous investigators are critically examined in light of the results. No single model leads to a proper scaling law for both normal and lateral penetration. (Author).

Book Description
The main aim of this experimental work was a detailed study of the influence of injection angle on the penetration and break-up of liquid fuel jets in a supersonic air stream. A particular goal was to incorporate that variable into the penetration correlations previously developed at VPI. This was accomplished. A secondary aim of the work was to assess the performance of liquid fuel jet injection from the top of a slender strut that protrudes out into the flow. This is one method that has been suggested for the 'mechanical' enhancement of penetration. The penetration behavior was found to be similar to that associated with injection from a flat plate. A result of particular interest was the discovery of waves with amazingly sharp crests on the windward side of the jets for downstream angled injection.
