An Alternative Scaling for Roughness Transitions in Turbulent Flows: The Role of the Internal Boundary Layer
Justin P. Cooke, George I. Park, Douglas J. Jerolmack +1
When turbulent boundary layer flows encounter abrupt roughness changes, an Internal Boundary Layer (IBL) forms. Equilibrium theory breaks down in the nonequilibrium IBL, which may…
Decoding planetary surfaces by counting cracks
S. Silver, K. Regős, G. Domokos +1
Planets are often covered with thin cracked shells. From mud films to lithospheres of rock or ice, fracture networks form two-dimensional (2D) tessellations of convex polygons whos…
The Evolution of Turbulence Producing Motions in the ABL Across a Natural Roughness Transition
Justin P. Cooke, Douglas J. Jerolmack, George I. Park
Landforms such as sand dunes act as roughness elements to Atmospheric Boundary Layer (ABL) flows, triggering the development of new scales of turbulent motions. These turbulent mot…
Athermal granular creep in a quenched sandpile
Nakul S. Deshpande, Paulo E. Arratia, Douglas J. Jerolmack
Creep is a generic descriptor of slow motions -- in the context of materials, it describes quasi-static deformation of a solid when subjected to stresses below the global yield, at…
