This book was released on 1986 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of surface roughness on the losses in the flow through a two-dimensional compressor cascade were studied. The cascade consisted of 7 NACA 65-A506 airfoils with 2-in. chords and aspect ratio of 1. The blades were mounted with a stagger angle of 16 deg, an angle of attack of 15 deg and a solidity of 1.5. The Reynolds number/foot was in excess of 2 million. Three blade configurations were evaluated: one smooth and two with different degrees of roughness applied to the first quarter chord. Hot wire/film anemometers measured velocities and turbulence intensities both in the wake and along the suction surface of the center blade. Surface roughness is shown to increase both boundary layer edge velocities and boundary layer thickness towards the trailing edge while advancing the transition point towards the leading edge. It is also shown to increase wake full thickness, momentum thickness, form factor, and total pressure loss coefficient while decreasing the velocity recovery immediately downstream of the trailing edge. Wake characteristics are most sensitive to an initial increase in roughness but the majority of the changes occur within the first half chord length distance downstream.

This book was released on 1990 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of surface roughness, freestream turbulence, and incidence angle on the performance of a two-dimensional compressor cascade were investigated. The test section consisted of seven NACA 65-A506 airfoils arranged in a linear cascade. Four different surface roughness conditions were applied to the first 25 percent chord on the suction surface of each of the five middle blades in the cascade. Freestream turbulence levels of approximately one and seven percent were used. Incidence angles of −3, zero and +3 degrees were investigated. Of the three parameters tested, freestream turbulence exerted the largest influence on blade performance. The total pressure loss coefficient increased with increased roughness and was reduced for large turbulence. Changes in flow incidence had a lesser effect on the performance of the blade.
