The granular Blasius problem

Autor: Stuart B. Dalziel, Nathalie Vriend, Jonathan Michael Foonlan Tsang

Publikováno v: Journal of Fluid Mechanics. 872:784-817

We consider the steady flow of a granular current over a uniformly sloped surface that is smooth upstream (allowing slip for $x) but rough downstream (imposing a no-slip condition on $x>0$), with a sharp transition at $x=0$. This problem is similar t

International audience; Environmental fluid mechanics underlies a wealth of natural, industrial, and, by extension, societal challenges. In the coming decades, as we strive towards a more sustainable planet, there are a wide range of Grand Challenge

Wake Induced Long Range Repulsion of Aqueous Dunes

Autor: Nathalie Vriend, Karol Bacik, Sean Lovett, Colm-cille Caulfield

Publikováno v: Physical Review Letters. 124

Sand dunes rarely occur in isolation, but usually form vast dune fields. The large scale dynamics of these fields is hitherto poorly understood, not least due to the lack of longtime observations. Theoretical models usually abstract dunes in a field

Force fluctuations at the transition from quasi-static to inertial granular flow

Autor: Karen E. Daniels, Amalia Thomas, Nathalie Vriend, Zhu Tang

We analyse the rheology of gravity-driven, dry granular flows in experiments where individual forces within the flow bulk are measured. We release photoelastic discs at the top of an incline to create a quasi-static erodible bed over which flows a st
