Description
Summary:The results of numerical simulation of a swirling flow of a liquid and a gas in contact with it in a closed cylindrical container in a gravitational field acting along the axis of the cylinder are presented. It is assumed that the bottom of the container rotates at a constant angular speed, its wall and top are stationary. Mathematical modeling of unsteady motion of a two-phase medium with a moving interface is based on the Volume of Fluid method. Finite volumes method is applied as discretization procedure to solve numerically the general differential equations. Velocity and pressure fields are obtained at the Reynolds number , Froude number , and Weber number . The features of the three-dimensional rotational motion of the fluid and gas are analyzed under the conditions of slow down action of the cylindrical wall of the container and its top.
