Effects of spatial gradients in thermophysical properties on the topology of turbulence in heated channel flow of supercritical fluids

C Azih, MI Yaras - Physics of Fluids, 2018 - pubs.aip.org
The current literature suggests that large spatial gradients of thermophysical properties,
which occur in the vicinity of the pseudo-critical thermodynamic state, may result in …

Measurements of the effects of streamwise riblets on boundary layer turbulence

DB Ancrum, MI Yaras - Journal of Fluids Engineering, 2017 - asmedigitalcollection.asme.org
This study presents experimental results on the effects of riblets on the coherent structures of
turbulence within a turbulent spot. The riblet spacings of the study correspond to 0.5 and 1.5 …

Measurements of the Effects of Streamwise Riblets on the Turbulence Structures in Boundary Layers

D Ancrum - 2016 - repository.library.carleton.ca
This study presents experimental results on the effects of streamwise-oriented riblets on the
coherent structures of turbulence. The riblet spacings correspond to 0.5 and 1.5 times the …

[PDF][PDF] Linearised Navier-Stokes equations and near-wall streaks in turbulent flow subject to drag reduction by wall oscillations

O Blesbois - 2013 - core.ac.uk
Spanwise wall-oscillation is a promising drag reduction technique in turbulent flows. A major
factor in drag reduction is the effect of the oscillations on the boundary layer coherent …
