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…
Coefficient of restitution of colliding viscoelastic spheres
Rosa Ramirez, Thorsten Poeschel, Nikolai V. Brilliantov +1
We perform a dimension analysis for colliding viscoelastic spheres to show that the coefficient of normal restitution depends on the impact velocity g as ε=1-γ_1g^{1/5}+γ_2g^{2…
