Flow Between Eccentric Rotating Cylinders

Abstract

In this numerical study of flow between eccentric cylinders, the size of the separation eddy and the position of the points of separation and reattachment are found to be Reynolds number dependent. The separation point moves in the direction of rotation upon increasing the Reynolds number, in contradiction to the first-order inertial perturbation theory of Ballal and Rivlin [1]. The numerical methods employed in this study include Galerkin’s procedure with B-spline test functions.
