Effect of Amplitude and Mean Angle of Attack on the Unsteady Surface Pressure of a Pitching Airfoil
Details of pressure distributions, on a two dimensional airfoil oscillating in pitch through stall, in a 0.8 0.8 m low-speed wind tunnel are presented. Pitching occurred about the airfoils quarter-chord axis. Pitch rate, Reynolds number, and oscillation amplitudes were varied to determine the effects on pressure and lift distributions. It was found that mean angle of attack and pitching amplitu...
متن کاملUnsteadiness in Flow over a Flat Plate at Angle-of-Attack at Low Reynolds Numbers
Flow over an impulsively started low-aspect-ratio flat plate at angle-of-attack is investigated for a Reynolds number of 300. Numerical simulations, validated by a companion experiment, are performed to study the influence of aspect ratio, angle of attack, and planform geometry on the interaction of the leading-edge and tip vortices and resulting lift and drag coefficients. Aspect ratio is foun...
متن کاملHigh Angle of Attack Aerodynamics
High angle of attack aerodynamics is inherently associated with: • separated flows, and thus nonlinear aerodynamics > one of the key aspects is the interaction of components, and in particular, vortex flows (vortex bursting is also an important effect) • heavily dependent on wind tunnel testing • connected with flight simulation to ensure good handling qualities > this means that large amounts ...
متن کاملA Computational Study about the Effect of Turbines Pitched Blade Attack Angle on the Power Consumption of a Stirred Tank
In this study, the stirring mechanism of shear-thinning fluids benefiting from four blades in turbulent flow is considered. The fluid is studied inside a stirred cylindrical tank with a flat bottom. The height of fluid is equal to the cylinder’s diameter and the impeller is positioned centrally. A CFD simulation has been carried out and three-dimensional turbulent flow is numerically analyzed u...
متن کاملThe Biometric Values of Affected and Fellow Eyes in Patients with Acute Attack of Primary Angle Closure
Background: It has been estimated that 67 million people worldwide are affected with a primary glaucoma and that one-third have primary angle closure glaucoma. We aimed to determine the biometric differences between the eyes of patients with acute attack of primary angle closure and their non-involved fellow eyes. Methods: Twenty eight patients with acute attack of primary angle closure were re...
