Abstract

The average isothermal fluid flow in an elongated parallelepiped that performs rotational vibration is studied experimentally. The structure and intensity of the average flows and the regularities of their transformation with variation of the vibration frequency are investigated. The dimensionless frequency is varied over a wide interval: from extremely low values where the fluid vibration is largely determined by the viscous forces up to high frequencies where the viscosity is important only in relatively thin Stokes boundary layers. The dimensionless complexes that determine the intensity of the average flows over the entire frequency range are found.
