Kinetic Integrals in the Kinetic Theoryof Dissipative Gases, velocity distribution function to the transport coefficients may be expressed in terms of functions of the collision integral which we call kinetic integrals. Although the evaluation of these functions is conceptually straightforward, technically it is frequently rather cumbersome. We report here a

Shock Waves in Granular Gases,hock and expansion waves propagating within granular gases. The analysis of model flows with shock and expansion waves shows that even smallest kinetic energy dissipations crucially affects such flows. We discuss the role of these waves for the fluidization of a granular flow by an obstacle, and of

Development of a Density Inversion in Driven Granular Gases, by a lower-density region. We employ the Navier-Stokes granular hydrodynamics to follow a density inversion as it develops in time. Assuming a dilute low-Mach-number flow, we derive a reduced time-dependent model of the late stage of the dynamics. The model looks especially simple in the Lagrangian

Kinetic Theory for Inertia Flows of Dilute Turbulent Gas-Solids Mixtures,in momentum and energy are incorporated in the conservation equations by using the Fokker-Planck technique. On the other hand, the effects of the solid particles’ kinetic motions and the solid-solid collisional interactions are formulated in the model by utilizing the approach of the kinetic theory

Van der Waals-Like Transition in Fluidized Granular Matter,ibrating wall and without gravity exhibit appearance, coagulation, and evaporation of bubbles. The instability is produced by the existence of a negative compressibility region, that is caused by the energy dissipation at collisions. The phenomenon is analogous to the spinodal decomposition of the g

Birth and Sudden Death of a Granular Cluster,d over the compartments, but if the shaking intensity is lowered this uniform distribution gives way to a clustered state. The clustering transition is experimentally shown to be of 2nd order for . = 2 compartments and of 1st order for . ≥ 3. In particular, the latter is hysteretic, involves long-li

Vibrated Granular Media as Experimentally Realizable Granular Gases,ce [4] of gravity. We show that a model with impact velocity dependent restitution coefficient is necessary to bring the simulations into agreement with experiments. We measure the scaling exponents of the granular temperature, collision frequency, impulse and pressure with the vibrating piston velo
