On nonviscous flows in cascades of blades
Abstract
A study of a model is given, describing nonviscous flows in blade machines whose walls can differ from cylindrical surfaces. The model overcomes a disadvantage of the well known Martensen method for plane, irrotational, incompressible flows in cascades of profiles, a model which can be applied with success if the walls of a channel, into which the blades are inserted, do not differ too much from concentric cylindrical surfaces. The threedimensional character of the stream fields is taken into consideration by introducing the socalled axial velocity ratio. A new stream function formulation of (generally incompressible) stream fields in cascades of blades is introduced, and a short survey is given on the mathematical and numerical study of this problem.
