Abstract

This paper propose a new potential flow method, useful in preliminary cascade profile design. By means of analytic function theory, flow field of a uniform stream around a staggered row of lifting cylinder has been solved. Then is presented a conformal mapping sequence capable to give from this flow field a blade cascade, characterised from a quasi-circular arc mean line. So it is possible to derive some different cascade design criteria, everyone founded on these theoretical background. Authors illustrate a procedure, not necessarily numerical, able to design zero-stagger profile cascade of whatever chord, solidity, thickness, inlet velocity and camber or alternatively lift.
