Book excerpt: The asymptotic solution of flow near the entrance of a heated straight pipe is obtained by perturbing the solution of flow in an unheated straight pipe. Two vortices result from motions of fluid particles induced by displacement of the boundary layer. The axial velocity has a concave profile and grows toward a uniform profile downstream. The downward stream caused by displacement of secondary boundary layer forces the axial velocity profile counterclockwise if the flow is from left to right. A favorable pressure gradient is generated on the bottom wall; an unfavorable pressure gradient is induced on the top wall.
