Fundamental Problems of Cascades for Transonic and Supersonic Stages of Turbomachines,
Abstract
The problems involved in the design of transonic and supersonic cascades are discussed and illustrated with some typical examples. The analysis leads to some general conclusions concerning the basic aerodynamic phenomena which determine the flow quality in these cascades: interaction of compression shocks and Mach waves, separation of the boundary layer and its consequences, and interaction of compression shocks and boundary layer. It is also pointed out that dissipation phenomena in the flow such as the effect of viscosity, vorticity, and thermal conductivity must also be taken into account. In conclusion, problems for future work in the field of flow in cascades are formulated. (Author)
