An Experimental Determination of Hydrodynamic Masses and Mechanical Impedances
Abstract
The study of the forces acting on a body due to the body's motion through a fluid is facilitated by the introduction of a 'hydrodynamic' mass, i. e., the mass of fluid that appears to be carried by the body accelerates in the fluid. Hydrodynamic masses have been computed from ideal fluid theory for mathematically 'easy' shapes - spheres, circular discs, etc. There are three methods available for the computation of hydrodynamic mass: the impedance approach, the kinetic energy method, and Darwin's 'drift' method. Each of these methods is presented in appendixes. Mechanical impedances have been computed for a very limited number of shapes.
