Abstract

The hydrodynamic forces and moment on submerged bodies of prolate ellipsoidal shape are investigated for two dimensional motion. The specific motion consisted of constant relative linear velocity of the fluid and body and small angular oscillation of the body about its geometric center. The average position of the long axis of the body was in the direction of constant linear motion. The components of the lateral force and of the moment proportional to angular position, velocity, and acceleration are measured for motion in water. These reactions are compared with the reactions derived from perfect fluid theory. It is concluded that the force proportional to angular position is the principal real fluid reaction not predicted by the perfect fluid theory. The deviations of the other components from the theoretical values are small.
