Abstract : The problem is considered of slow, viscous flow about a rotating sphere located at the center of an infinitely long circular cylinder which rotates at a different speed about the same axis as the sphere. The velocity distribution in the flow field and the couple required to maintain steady rotation are obtained. Results show the equivalence of this problem with that of potential flow past a sphere inside a cylindrical duct. A numerical example is worked out. (Author)
