Supplements to "Theory of secondary flow in cascades"

On the previous report “Theory of Secondary Flow in Cascades”, some matters to be supplemented, improved or revised are explained, together with the further results which were obtained since then. The reason why the theory of secondary flow in cascades has not yet fully succeeded in explaining the three-dimensional character of cascade flows, the fact that we should notice the vortex metamorphosis and the trailing shed vortex being matters which have no direct connection each other, and the wake of cascade blade is the key to solve the relation between the axisymmetric flow and the actual three-dimensional flow in turbo-machinery, are stated in this report.
