The results of an experimental and theoretical investigation of thermodynamic effects on developed cavitation are presented. Distributions of temperature and pressure were measured for zero- and quarter-caliber ogives over a wide range of velocities, temperatures and cavity lengths. The semi-empirical entrainment theory is used to correlate the measured temperature depressions in the cavity. This theory relates the maximum temperature depression expressed in dimensionless form as the Jakob number in terms of the dimensionless numbers of Nusselt, Reynolds, Froude, and Peclet, and dimensionless cavity length. The results show that, in general, the temperature depression increases with cavity lengths and temperature.

Theoretical expressions for the lift, drag, and center of pressure of super-cavitating hydrofoils of arbitrary section, aspect ratio, and depth of submersion are developed for the zero-cavitation-number case.

Abstract: The existing two-dimensional theory for the characteristics of supercavitating hydrofoils operating at zero cavitation number is modified to include the effects of camber, aspect ratio, and depth of submersion. For a comparison with the theory, two aspect-ratio-1 hydrofoils, a flat plate and one with a cambered lower surface, were tested by operating them near the water surface so that their upper surfaces were completely ventilated. The data obtained verified the theory to within 3 percent. Some experimental data are also presented for the models operating at nonzero cavitation number for both air and water-vapor-filled cavities.

A series of experiments were performed where single molten tin droplets of known size, shape and temperature were dropped from a low height into a pool of distilled water. The pressure waves emanating from the hot droplets were recorded by a transducer in the coolant for varying initial droplet and pool temperatures. The results obtained show well defined patterns of pressure frequency and magnitude behavior. Application of the results to the acoustic cavitation theory of fragmentation shows that the pressure excursions within the molten tin are considerably less severe than was predicted. The likelihood that acoustic cavitation caused the observed fragmentation is therefore considerably diminished. Further, the results strongly suggest that spontaneous nucleation of the coolant did not cause the observed fragmentation, while it appears that another mechanism linked to the observed dwell time behavior was responsible. Further theoretical and experimental work is required to establish the nature of this mechanism.

The cavitation in nozzles on airfoils of various shape and on a sphere are experimentally investigated. The limits of cavitation and the extension of the zone of the bubbles in different stages of cavitation are photographically established. The pressure in the bubble area is constant and very low, jumping to high values at the end of the area. The analogy with the gas compression shock is adduced and discussed. The collapse of the bubbles under compression shock produces very high pressures internally, which must be contributory factors to corrosion. The pressure required for purely mechanical corrosion is also discussed.
