Experimental Comparisons

The development of supercritical cascades follows experience with supercritical single profiles. In cascade arrangement strong inter-blade influences exist in the transonic region, so that a desired pressure distribution, starting from the contour shape, is not easy to realize. For these cases, a design method has been developed in which the boundary conditions can be prescribed in a simple and clear manner. Thickness and deflection are not restricted, since the full potential equation is treated. Variation of the axial velocity density ratio is provided for. The solution by relaxation leads to short computing times. Experimental comparisons for turbine and compressor cascades show the applicability of the method.

Recent Trends

This paper reviews recent trends of analysis of aeroacoustic problems via traditional CFD techniques, as well as analysis of aerodynamic problems via modern aeroacoustic methods. Individual methods are described and tendencies of evolution are indicated. A generalized version of the full potential equation is derived. These two complementary forms of research converge towards the integration of Aeroacoustics and Aerodynamics into a single framework, where the computer serves as an integration tool.
