Motion of a variable body in an ideal liquid. (English. Russian original) Zbl 1046.76008
J. Appl. Math. Mech. 65, No. 4, 579-587 (2001); translation from Prikl. Mat. Mekh. 65, No. 4, 592-601 (2001).
The authors study the motion of a deformable body in an infinite ideal fluid which performs irrotational motion and rests at infinity. Under some assumptions on the variation of body form and mass geometry, the equations of motion are derived and their properties are investigated. It is shown that for unequal added masses the body can move from one position to an other position solely due to the change in mass geometry.
