Phase-coexisting patterns, horizontal segregation and controlled convection in vertically vibrated binary granular mixtures
I. H. Ansari, N. Rivas, M. Alam
We report new patterns, consisting of coexistence of sub-harmonic/harmonic and asynchronous states [for example, a granular gas co-existing with (i) bouncing bed, (ii) undulatory s…
Mesoscopic electrohydrodynamic simulations of binary colloidal suspensions
Nicolas Rivas, Stefan Frijters, Ignacio Pagonabarraga +1
A model is presented for the solution of electrokinetic phenomena of colloidal suspensions in fluid mixtures. We solve the discrete Boltzmann equation with a BGK collision operator…
Experiments and characterization of low-frequency oscillations in a granular column
Loreto Oyarte-Gálvez, Nicolás Rivas, Devaraj van der Meer
The behaviour of a vertically vibrated granular bed is reminiscent of a liquid in that it exhibits many phenomena such as convection and Faraday-like surface waves. However, when t…
