Abstract
This paper is concerned with the added mass matrix for a mechanical st ructure vibrating in an incompressible liquid. It is shown in particul ar that this matrix does not depend on viscosity and, from this fact, can be calculated as if the fluid is perfect. The viscous effect on th e mechanical system can then be represented by a damping term of type time-convolution. The presence of a Rowing fluid around the structure leads to additional damping terms proportional to the fluid density.
