To investigate the time-dependent non-axisymmetric flow between two rotating cylinders, or the so-called Couette-Taylor problem, a numerical model to solve the three-dimensional Navier -Stokes equations is established. The projection method is employed to obtain the pressure Poisson equation first.

β¦ Synopsis
A spectral method is used to study numerically flow between two concentric rotating spheres. Analytical expressions of eigenfunctions of a Stokes operator in the spherical gap region are presented, numerical experiments are carried out by applying these expressions to the spectral approximation of spherical Couette flow, and numerical results are given.

The Bingham fluid flow between two concentric cylinders is studied using numerical simulation. The cylinders are assumed to rotate independently, and with an imposed axial sliding. The flow field is decomposed with linearity arguments of the base circular Couette shear flow and corresponding deviati
A new numerical procedure for predicting multiple solutions of Taylor vortices in a spherical gap is presented. The steady incompressible Navier-Stokes equations in primitive variables are solved by a finitedifference method using a matrix preconditioning technique. Routes leading to multiple flow s
