Investigation of the influence of radial grooves on the flow in an eccentrically deposited annulus using CFD numerical simulation
Original language description
This paper evaluates the influence of radial grooves in the eccentrically deposited annulus using by mathematical modeling of fluid flow through each grooves. The inner cylinder (rotor) is eccentrically deposited and its movement is composed of two movements (rotation and precession). The outer cylinder is stationary and has radial grooves. In the first phase is defined a mathematical model of the flow, which is then applied to the 3D model of narrow gap with radial grooves. In this paper are present several variants of the computational domain with regard to the number of radial grooves. Based on the results of numerical simulations are evaluated basic variables such as pressure and velocity. There are also evaluated radial force (Fr) and axial force(Fa) acting on the rotor for different boundary conditions (different speeds of rotation and precession). Subsequently, the pressure gradients (p) are evaluated between the radial grooves for different computational domain. Results are co
