Available in PDF, EPUB and Kindle. Book excerpt: A previously developed theory for the calculation of a three-dimensional boundary layer along any curved axisymmetric wall surface is summarized. In addition, new defect force correlations taken into account the interactions between blades and end-wall boundary layer flows, in particular tip clearance effects, relative motion and secondary losses are included. Velocity profiles are reconstructed from the integral boundary layer thicknesses by use of velocity profile models defined in the meridional and angular directions. The different aspects of the theory are tested systematically on various configurations. It is shown that the overall behaviour of axial compressor boundary layers can be simulated with the present method and that the defect force correlations are able to simulate all the secondary flow effects.

This book was released on 1948 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the further development of axial blowers into highly loaded flow machines, the influence of the diameter ratio upon air output and efficiency gains in significance. Clarification of this matter is important for single-stage axial compressors, and is of still greater importance for multistage ones, and particularly for aircraft power plants. Tests with a single-stage axial blower gave a decrease in the attainable maximum pressure coefficient and optimum efficiency as the diameter ratio increased. The decrease must be ascribed chiefly to the guide surface of the hub and housing between the blades increasing with the diameter ratio.

This book was released on 1988 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A boundary layer control device was designed to change significantly the case-wall boundary layer thickness entering a large-scale, multistage axial compressor. The device was intended to double the boundary layer thickness in order to evaluate the influence of the inlet boundary layer in controlled tip clearance experiments being conducted on the compressor. The boundary layer characteristics expected to be produced by the control device were predicted empirically and experimental verification was required. Kiel, cobra, and impact probes were used in the experiments and pressures were recorded manually using water manometers. The geometry of the boundary layer control device, an annular array of spires, was derived from shapes developed for simulating the atmospheric boundary layer in large rectangular section wind tunnels. A significantly thicker boundary layer was measured in the compressor than was intended. However, the results were interpreted and recommendations were made for geometry changes necessary to achieve the intended control for the tip clearance investigation.
