Particle-scale structure of granular suspensions
Santos Bravo Yuste, Antonio M. Puertas
Granular suspensions are intrinsically nonequilibrium systems in which dissipative grain-grain collisions coexist with solvent-induced forcing. We study the particle-scale structur…
Particles, trajectories and diffusion: random walks in cooling granular gases
Santos Bravo Yuste, Rubén Gómez González, Vicente Garzó
We study the mean-square displacement (MSD) of a tracer particle diffusing in a granular gas of inelastic hard spheres under homogeneous cooling state (HCS). Tracer and granular ga…
Search and escape of mortal random walkers
E. Abad, S. B. Yuste
We review some representative results for first-passage problems involving so-called mortal or evanescent walkers, i.e., walkers with a finite lifetime. The mortality constraint pl…
An Adaptive Difference Method for Variable-Order Diffusion Equations
Joaquín Quintana-Murillo, Santos Bravo Yuste
An adaptive finite difference scheme for variable-order fractional-time subdiffusion equations in the Caputo form is studied. The fractional time derivative is discretized by the L…
Gaseous Diffusion as a Correlated Random Walk
Santos Bravo Yuste, Rubén Gómez González, Vicente Garzó
The mean square displacement per collision of a molecule immersed in a gas at equilibrium is given by its mean square displacement between two consecutive collisions (mean square f…
The pseudo-two-dimensional dynamics in a system of macroscopic rolling spheres
M. A. López-Castaño, J. F. González-Saavedra, A. Rodríguez-Rivas +3
We study in this work the dynamics of a collection of identical hollow spheres (ping-pong balls) that rest on a horizontal metallic grid. Fluidization is achieved by means of a tur…
