Experimental study of a turbulent boundary layer with a rough-to-smooth change in surface conditions at high Reynolds numbers

Mogeng Li, Charitha M. de Silva, Daniel Chung +3

This study presents an experimental dataset documenting the evolution of a turbulent boundary layer downstream of a rough-to-smooth surface transition. To investigate the effect of…

Recovery of the wall-shear stress to equilibrium flow conditions after a rough-to-smooth step-change in turbulent boundary layers

Mogeng Li, Charitha M. de Silva, Amirreza Rouhi +4

This paper examines recovery of the wall-shear stress of a turbulent boundary layer that has undergone a sudden transition from a rough to a smooth surface. Early works of Antonia…

Evidence that superstructures comprise of self-similar coherent motions in high boundary layers

Rahul Deshpande, Charitha M. de Silva, Ivan Marusic

We present experimental evidence that the superstructures in turbulent boundary layers comprise of smaller, geometrically self-similar coherent motions. The evidence comes from ide…

Mitigation of the Turbulence within an Arteriovenous Fistula with a Stent Implantation

Sanjiv Gunasekera, Tracie Barber, Olivia Ng +3

The transitional flow which initiates within the junction (anastomosis) of an arteriovenous fistula (AVF) is known to be a contributing factor in the onset of vascular disease. A n…

Self-similar geometries within the inertial subrange of scales in boundary layer turbulence

Michael Heisel, Charitha M. de Silva, Gabriel G. Katul +1

The inertial subrange of turbulent scales is commonly reflected by a power law signature in ensemble statistics such as the energy spectrum and structure functions - both in theory…

Data-driven enhancement of coherent structure-based models for predicting instantaneous wall turbulence

Rahul Deshpande, Charitha M. de Silva, Myoungkyu Lee +2

Predictions of the spatial representation of instantaneous wall-bounded flows, via coherent structure-based models, are highly sensitive to the geometry of the representative struc…

Statistics of turbulence in the energy-containing range of Taylor-Couette compared to canonical wall-bounded flows

Dominik Krug, Xiang I. A. Yang, Charitha M. de Silva +4

Considering structure functions of the streamwise velocity component in a framework akin to the extended self-similarity hypothesis (ESS), de Silva \textit{et al.} (\textit{J. Flui…
