Tabulation and Summary of Thermodynamic Effects Data for Developed Cavitation on Ogive-Nosed Bodies.

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 m/sec to 36.6 m/sec. 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 (L/D). (Author)
