The formation and amplification of streamwise velocity perturbations induced by cross-
stream disturbances is ubiquitous in shear flows. This disturbance growth mechanism, so …

Transitional–turbulent spots bridge the deterministic laminar state with the stochastic
turbulent state and affect the transition zone length in engineering flows. Turbulent spot …

Vertical axis wind turbines (VAWTs) have received growing interest for off-shore application
and in the urban environments mainly due to their omni-directional capability, scalability …

A nominally-zero-pressure-gradient incompressible boundary layer over a smooth flat plate
was simulated for a continuous momentum thickness Reynolds number range of 80≤ …

A recent assessment of available direct numerical simulation (DNS) data from turbulent
boundary layer flows (Schlatter & Örlü, J. Fluid Mech., vol. 659, 2010, pp. 116–126) showed …

Comparisons of inflow conditions for large-eddy simulations of turbulent, wall-bounded flows
are carried out. Consistent with previous investigations, it is found that the spectral content of …

an eerie type of chaos can lurk just behind a facade of order, and yet deep inside the chaos
lurks an even eerier type of order.” Douglas Hofstadter Bypass transition to turbulence in …

The role of free-stream turbulence (FST) in the hydrodynamic instability mechanisms and
transition to turbulence in laminar separation bubbles (LSBs) was investigated using direct …

Free-stream turbulence (FST) is perhaps the most important source inducing by-pass
transition in boundary layer flows. The present study describes the initial energy growth of …

In this study we characterize the turbulence, by means of energy spectra, characteristic
turbulence length scales, energy dissipation, kinetic energy decay rate etc., behind a set of …
