Purpose The purpose of this paper is to study the dynamical properties of a rotating rigid body (RB) containing a viscous incompressible fluid. Design/methodology/approach The Reynolds number is assumed to be small so that the governing equations can be easily obtained, and the asymptotic technique is used to solve the problem. Findings The effects of the various body parameter values on the motion’s behavior are theoretically elucidated, which can be used for optimization of the charged RB. Originality/value This paper finds the missing piece of the puzzle when it comes to the rotating RB containing a viscous fluid; it clearly elucidates graphically how the body parameters affect its dynamical properties.
