Dynamics of fluid-fluid displacements in a model rough fracture beyond the quasistatic limit: A spectral approach
Mykyta Chubynsky, Jordi Ortin, Marco Dentz +1
In fluid-fluid displacements in porous and fractured materials, viscous friction in microscale interfacial (Haines) jumps is intimately linked to macroscale energy dissipation and…
Laminar and Turbulent Flow in Wavy Pipes under Strong Wall Modulations
Ismail El Mellas, Juan J. Hidalgo, Marco Dentz
We study laminar, transitional and turbulent flow in wavy pipes using direct numerical simulations for bulk Reynolds numbers between 1-5300. Flow behaviors are analyzed in terms of…
Fluid Deformation in Random Unsteady Flow
Daniel Lester, Marco Dentz
Fluid deformation controls myriad processes in random flows including mixing and dispersion, stress development in complex fluids, colloid transport and deposition, droplet breakup…
Line Stretching in Random Flows
Daniel Lester, Marco Dentz
How finite-sized material lines stretch in chaotic (mono-scale) and turbulent (multi-scale) flows remains a central but unresolved problem that governs mixing, transport and reacti…
