In the paper we consider the motion of a rigid body in a boundless volume of liquid. The body is set in motion by redistribution of internal masses. The mathematical model employs the equations of motion for the rigid body coupled with the hydrodynamic Navier–Stokes equations. The problem is mostly dealt with numerically. Simulations have revealed that the body's trajectory is strongly governed by viscous effects.
Mots-clés : self-propulsion
Keywords: Navier–Stokes equations, viscous vortical motion, numerical methods.
