Journal ArticleDOI
The Many Faces of Turbine Surface Roughness
TL;DR: In this paper, contact stylus measurements of surface roughness on in-service turbine blades and vanes were performed. And the results showed that significant spatial variations are evidenced and transitions from rough to smooth surface conditions are remarkably abrupt in some cases.
Journal ArticleDOI
Turbine Separation Control Using Pulsed Vortex Generator Jets
TL;DR: In this article, the application of pulsed vortex generator jets to control separation on the suction surface of a low-pressure turbine blade is reported, and the results show that the effect of the pulsed generator jets is comparable to that of steady jets with an order of magnitude less massflow.
Journal ArticleDOI
A Review of Surface Roughness Effects in Gas Turbines
TL;DR: In this article, the effects of surface roughness on gas turbine performance are reviewed based on publications in the open literature over the past 60 years, and the conclusion remains that considerable research is yet necessary to fully understand the role of roughness in gas turbines.

TL;DR: Keratoconic eyes demonstrated less resistance to deformation than normal eyes with similar IOP and the stiffness parameters may be useful in future biomechanical studies as potential biomarkers.
Journal ArticleDOI
Control of Low-Pressure Turbine Separation Using Vortex-Generator Jets
TL;DR: In this article, the application of vortex-generator jets to control separation on the suction surface of a low-pressure turbine blade is reported, and the results show that above a minimum blowing ratio, which is dependant on the injection location, the pressure loss in the modified blade's wake is reduced by a factor of between two and three.
