Clustering and fluidization in a one-dimensional granular system: molecular dynamics and direct-simulation Monte Carlo method
Jose Miguel Pasini, Patricio Cordero
We study a 1-D granular gas of point-like particles not subject to gravity between two walls at temperatures T_left and T_right. The system exhibits two distinct regimes, depending…
Thermal convection in fluidized granular systems
Rosa Ramirez, Dino Risso, Patricio Cordero
Thermal convection is observed in molecular dynamic simulation of a fluidized granular system of nearly elastic hard disks moving under gravity, inside a rectangular box. Boundarie…
Hydrodynamic theory for granular gases
Rosa Ramirez, Dino Risso, Rodrigo Soto +1
A granular gas subjected to a permanent injection of energy is described by means of hydrodynamic equations derived from a moment expansion method. The method uses as reference fun…
Free Thermal Convection Driven by Nonlocal Effects
Jorge Ibsen, Rodrigo Soto, Patricio Cordero
We report and explain a convective phenomenon observed in molecular dynamics simulations that cannot be classified either as a hydrodynamics instability nor as a macroscopically fo…
