The practicality and accuracy of many existing methods of local skin friction measurement
suffer when the boundary layer flow under consideration is non-canonical. Such …

Active control of a turbulent boundary layer has been experimentally investigated with a
view to reducing the skin-friction drag and gaining some insight into the mechanism that …

Here, we detail and analyse a multi-resolution particle image velocity measurement that
resolves the wide range of scales prevalent in a zero pressure gradient turbulent boundary …

Wall shear stress, pressure, and heat flux are of significant importance in engineering
applications. In this two-part study, we investigate the compressibility effects on wall shear …

The relationship between skin friction and the surface optical flow (SOF) in viscous flows is
discussed based on the evolution equations of surface temperature, scalar, and enstrophy …

A direct numerical simulation of the Navier–Stokes equations is used to compute the space–
time correlations of velocity fluctuations in a turbulent channel flow. By examining the …

Direct numerical simulation of flow in a turbulent channel with a random rough bottom wall is
performed at friction Reynolds number. The rough surface corresponds to the experiments of …

A turbulent boundary layer modified by spanwise wall oscillations is experimentally studied
in a water channel by means of hot-film anemometer and laser Doppler velocimeter. The …

The present work deals with the characteristics of the streamwise component of the
fluctuating wall-shear stress τ w′ in a smooth-wall turbulent boundary layer. A near-wall …

Instantaneous velocity and wall shear stress measurements are conducted in a turbulent
channel flow in the Kármán number range of Reτ= 74–400. A one-dimensional LDA system …
