An Analysis of Developing Turbulent Flow between a Moving Cylinder and a Concentric Tube

Abstract

A numerical analysis is made of developing and developed turbulent flow in the annular region between a cylinder moving at constant velocity within a fixed concentric tube. Turbulent shear is modeled by eddy viscosity, an a uniform velocity is assumed at the entrance to the annular region. The computations extend and modify the method of Sud and Chaddock (1981) to arbitrary Reynolds numbers and radius ratios. Approximate formulas are given for both developing and developed values of pressure drop, shear stress on the inner and outer walls, and total cylinder drag. (jd)
