Rigid-like fluid motion

Selamoğlu, S.
An arbitrary, rigid-like, unsteady flow of a fluid under constant, uniform body force is shown to be impossible in general unless the flow is a translation parallel to the body force. Consequently, the known steady-state, rigid-like fluid flows having horizontal components could be reached from a state of rest by the aid of dissipative processes only; and any two such steady states cannot be tied by an unsteady rigid-like flow program. Examples are given for approximately —rigid-like plane motion of a liquid under gravity, which are of practical significance from the view-point of transportation of liquids, as well as of large solid structures.
