The engineering interest about windblown sand is dictated by the harmful interactions
between sand and a number of human infrastructures in arid environments. Particularly, the …

Free-stream turbulence (FST) and its effect on boundary-layer transition is an intricate
problem. Elongated unsteady streamwise streaks of low and high speed are created inside …

Streamwise rolls and accompanying streamwise streaks are ubiquitous in wall-bounded
shear flows, both in natural settings, such as the atmospheric boundary layer, as well as in …

This paper on airfoil turbulence interaction noise reveals the nature of the relation between
the distortion type of turbulent structures and radiated far-field noise. The turbulence …

Experiments were conducted to study the transition and flow development in a laminar
separation bubble (LSB) formed on an aerofoil. The effects of a wide range of free-stream …

Turbulent motions in a fluid decay at a certain rate once stirring has stopped. The role of the
most basic parameter in fluid mechanics, the Reynolds number, in setting the decay rate is …

A preliminary version of this paper was presented at the AIAA Aviation 2020 forum (Paper
2020-2525). This paper provides an insight into the grid generated turbulence for …

In recent years, with the development of the wind power industry and the increase in the
number of wind turbines, the condition monitoring of blades and the detection of damage are …

Generating atmospheric turbulence in wind tunnels is an important issue in the study of wind
turbine aerodynamics. A turbulent inlet is usually generated using passive grids. However …

The aerodynamic performance of lifting surfaces operating at low Reynolds number
conditions is impaired by laminar separation. In most cases, transition to turbulence occurs …
