Added Masses of Interacting Bodies

If a body is moving in a fluid close to other bodies (moving or not), then its added masses differ from the added masses corresponding to motion in an infinite fluid. This difference arises due to different boundary conditions: for an isolated body in an infinite fluid one has only a boundary condition (water-tightness) on the body surface and a boundary condition at infinity. In the presence of other bodies one should also impose boundary conditions on their surfaces. A partial case of such a situation is the motion of a body near a wall, which in the case of an ideal fluid can be substituted by the mirror image of the body. In this chapter we consider added masses of interacting bodies and added masses of bodies moving near hard walls.
