Abstract
Basic problems in fuel-spray research are discussed. Progress is summarized on (1) studies of the disintegration mechanisms of flat and conical liquid sheets and the mechanism of flow through swirl-chamber nozzles, (2) combustion studies, (3) the development of a rapid spray analyzer, and (4) the development of a photographic technique. A photographic method was devised which did not disturb the spray. Measurements were made of the size distribution of the spray drops, the spatial location of drops of various sizes, and the velocities of the drops. A spray analyzer was constructed which gave a quick evaluation of hollow-cone nozzles; a permament record of the patternization is obtained for each test. The cone angle was measured with an attachment. A description is presented of the fluid behavior within the swirl chamber and of the spray formation after fluid emergence from the chamber to form a hyperbolic sheath. The over-all burning efficiency of the combustion chamber was substantially constant for wide variations in the patternization of a given nozzle over a range of conditions. Relatively hot regions were produced with an uneven patternization which may cause hot spots and temperature stratification in the gases striking the turbine blades. Variations in the incoming air-flow patterns produce effects similar to those of poor patternization.
