Near-wall cylinder wake deflection and aero-optical characteristics

Physics of Fluids
As a passive flow controller, a circular cylinder is commonly employed in airborne optical systems to disturb the incoming flow and thereby mitigate aerodynamic interference with optical components. Under near-wall constraints, the spacing between the cylinder and the wall exerts a significant influence on several flow characteristics, including wake ...

Analysis of Strouhal number based equivalence of pitching and plunging airfoils and wake deflection

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2014
Numerical simulations have been used to analyze the equivalence of pitching and plunging motions found in a flapping NACA0012 airfoil. Two-dimensional incompressible Navier–Stokes equations are solved at Reynolds number of 10 3 over a range of Strouhal numbers.

Pervasiveness of Excessive Segmental Bridge Deflections: Wake-Up Call for Creep

ACI Structural Journal, 2011
An obsolete standard recommendation for creep design led to significant underestimation of the observed 18-year deflections of the Koror-Babeldaob (KB) Bridge in the island nation of Palau. A search for data on similar bridges revealed that 56 other large-span, prestressed concrete, segmentally erected box girders (66 by the time of proof) have been ...

A Study of Intensified Wake Deflection by Multiple Yawed Turbines based on Large Eddy Simulations

33rd Wind Energy Symposium, 2015
Yawed turbines are known to cause wake deflection, which has been considered in wake controlling concepts for the purpose of reducing wake loss. However, an isolated yawed turbine can only produce a small amount of wake shifting for downstream turbines, resulting in an overall loss of power output.
