Thermodynamic Effects on Desinent Cavitation on Hemispherical Nosed Bodies in Water at Temperatures From 80 Deg F to 260 Deg F

Abstract

The theoretical analysis and experiments are presented for desinent (limited) cavitation on hemispherical nosed bodies in water at temperatures from 80 to 260 deg F. The models were 1/4 in. and 1/2 in. in diameter and were tested at velocities of 44, 76, and 132 fps in the NASA cavitation tunnel at The Pennsylvania State University. The theoretical model which most closely agrees with experiment is the isothermal case for surface nuclei. Arguments are presented which tend to support the validity of this result.
