✦ Synopsis


Ah&act-Profiles of pressure, velocity gradient, and local mass transfer rate on the surface of a sphere in a close packed cubic array are interpreted in terms of visual studies which determine the singularities of the limiting streamlines. Contact points are found to play an important role and studies of flow through a single layer of spheres are used to help determine their influence. On the basis of these experiments, a flow pattern is suggested for Reynolds numbers close to that for a transition to unsteady flow. Some of the problems associated with applying boundary layer theory are discussed.
