Extract

This report describes the design of an annular entry for the axisymmetric flow into a circular duct, shaped so that the wall velocity gradients are favourable to the development of the boundary layer flow. As a first step the accelerating flow around a two-dimensional 90° duct bend with favourable gradients was obtained. This shape was modified and the axisymmetric flow pattern through it obtained by a combination of electrical analogue and relaxation methods and then checked by experiment. The favourable gradients were retained in the axisymmetric flow.
