Flow induced by an oscillating plate in a particle-fluid mixture
Abstract
The flow induced in a particle-fluid mixture by an infinite flat plate, which oscillates in its own plane, is studied theoretically, assuming Basset-Boussinesq-Oseen's form of the interaction force between a particle and fluid. The influence of frequency and density ratio on the boundary-layer thickness, the wavelength of the viscous wave, the particle velocity and the viscous stress is examined in a discussion on the general properties of the basic equations and analytical solutions. It is shown that the time-dependent interaction force between a particle and fluid is important in the case of high frequency and the particle lighter than the fluid. It is not appropriate to assume Stokes' formula in these cases.
