Zusammenfassung:
In this paper we consider the steady sedimentation of a uniform distribution of particles in a uniformly rotating liquid, and examine its stability by solving the set of conservation equations for a two-phase flow. The sixth order algebraic equation in the frequency which results from the perturbation equations is solved numerically. The effects of the variation of the rotation rate, sediment concentration, and vertical wave numbers of small disturbances are discussed and presented graphically.
