Computational Fluid Dynamics Methods for Low Reynolds Number Precessing/Spinning Incompressible Flows

Abstract

Three dimensional, steady-state, laminar, fully viscous Navier-Stokes simulations were used to predict the behavior of incompressible liquids that were undergoing steady spin and steady precession at a fixed precession angle. These numerical simulations can predict steady viscous and pressure moments. These moments tend to increase the precession angle and reduce the spin rate of the container system. For a completely filled cylinder, liquid-induced roll and side (yaw) moments were computed as functions of cylinder height to diameter. Keywords: Finite difference, Incompressible flow, Liquid-filled projectile, Liquid moment, Low reynolds number, Rotating liquids.
