Hydrodynamic Effects of Harmonic Acceleration

Abstract

Circular disks, cylinders, and tandem disks are oscillated in water and the hydrodynamic mass and damping determined. Correlation with the acceleration modulus and nondimensional amplitude of oscillation is shown. Equations are given for coefficients of hydrodynamic inertia, drag, and total resistance for disks and methods of application to sonobuoy suspension systems are outlined.
