Abstract:

Thermodynamic effects data for developed cavitation on zero and quarter caliber ogives in Freon 113 and water are tabulated and summarized. These data include temperature depression Delta T, flow coefficient C sub Q and various geometrical characteristics of the cavity. For the Delta T tests, the free-stream temperature T sub infinity varied from 35 C to 95 C in Freon 113 and from 60 C to 125 C in water for a velocity range of 19.5 msec to 36.6 msec. Two correlations of the Delta T data by the entrainment method are presented. These correlations involve different combinations of the Nusselt, Reynolds, Froude, Weber and Peclet numbers and dimensionless cavity length LD. Author
