Abstract
When the liquid for cooling is sprayed into supersonic flows with high temperature, it is important to understand cooling effects by evaporation on the flows. It is required that the spray used for this purpose should be miniature to make the effects on the flow as small as possible and the droplet discharged should be evaporated easily. The foundational experiments are done to develop the atomizer which fulfills these conditions. In the present study, experimental research on figures and capacity of swirl chamber, and the figures of jet nozzle etc. is performed, and the design parameters of spray to get the desirable mist condition are clarified.
