Turbulent flow over transitionally rough surfaces with varying roughness densities
M. MacDonald, L. Chan, D. Chung +2
We investigate rough-wall turbulent flows through direct numerical simulations of flow over three-dimensional transitionally rough sinusoidal surfaces. The roughness Reynolds numbe…
Direct numerical simulation of high aspect ratio spanwise-aligned bars
M. MacDonald, A. Ooi, R. García-Mayoral +2
We conduct minimal-channel direct numerical simulations of turbulent flow over two-dimensional rectangular bars aligned in the spanwise direction. This roughness has been often des…
Near wall coherence in wall-bounded flows and implications for flow control
Milad Samie, Woutijn Baars, Amirreza Rouhi +4
Opposition-control of the energetic cycle of near wall streaks in wall-bounded turbulence, using numerical approaches, has shown promise for drag reduction. For practical implement…
On the mixing length eddies and logarithmic mean velocity profile in wall turbulence
Michael Heisel, Charitha M. de Silva, Nicholas Hutchins +2
Since the introduction of the logarithmic law of the wall more than 80 years ago, the equation for the mean velocity profile in turbulent boundary layers has been widely applied to…
