Dependence of square cylinder wake on Reynolds number
Honglei Bai,Md. Mahbub Alam +1 more
TL;DR: In this article, the wake of a square cylinder is investigated for Reynolds number Re < 107, and the dependence on Re of the recirculation bubble size or vortex formation length, wake width, shear-layer transition, time-mean drag force, and Strouhal number is discussed in detail.
Journal ArticleDOI
Blade Shape Optimization of the Savonius Wind Turbine Using a Genetic Algorithm
TL;DR: Compared to the wind turbine with semicircular blades, the Savonius turbine with optimal blades and a tip speed ratio (TSR) of 0.8 achieved significant improvement on the time-averaged power coefficient, suggesting that the Sav onius wind turbine has great potential to be applied in the real urban environment.
Journal ArticleDOI
Cross -stream stereoscopic particle image velocimetry of a modified turbulent boundary layer over directional surface pattern
Kevin Kevin,Jason Monty,Honglei Bai,Honglei Bai,Gokul Pathikonda,Gokul Pathikonda,B Nugroho,Julio Barros,Julio Barros,Kenneth T. Christensen,Kenneth T. Christensen,Kenneth T. Christensen,Nicholas Hutchins +12 more
TL;DR: In this paper, a turbulent boundary layer developed over a herringbone patterned riblet surface is investigated using stereoscopic particle image velocimetry in the cross-stream plane at Reτ ≈ 3900.
Journal ArticleDOI
Active control of a turbulent boundary layer based on local surface perturbation
TL;DR: In this article, a spanwise-aligned array of piezo-ceramic actuators was employed to generate a transverse travelling wave along the wall surface, with a specified phase shift between adjacent actuators.
Journal ArticleDOI
Effects of large spanwise wavelength on the wake of a sinusoidal wavy cylinder
TL;DR: In this article, a sinusoidal wavy cylinder with a large spanwise wavelength and a constant wave amplitude was investigated using three dimensional (3D) large eddy simulation (LES) at a subcritical Reynolds number Re=3×103, based on incoming free stream velocity (U∞) and Dm.
