In this regime, grains only touch each other during collisions and hence, kinetic theory is a very useful tool to study granular flows. The main difference with respect to ordinary or molecular fluids is that grains are macroscopic and so, their collisions are inelastic. Given the interest in the effects of collisional dissipation on granular media under rapid flow conditions, the emphasis of this book is on an idealized model (smooth inelastic hard spheres) that isolates this effect from other important properties of granular systems. In this simple model, the inelasticity of collisions is only accounted for by a (positive) constant coefficient of normal restitution. The author of this monograph uses a kinetic theory description (which can be considered as a mesoscopic description between statistical mechanics and hydrodynamics) to study granular flows from a microscopic point of view. In particular, the inelastic version of the Boltzmann and Enskog kinetic equations is the starting point of the analysis. Conventional methods such as Chapman-Enskog expansion, Grad’s moment method and/or kinetic models are generalized to dissipative systems to get the forms of the transport coefficients and hydrodynamics. The knowledge of granular hydrodynamics opens up the possibility of understanding interesting problems such as the spontaneous formation of density clusters and velocity vortices in freely cooling flows and/or the lack of energy equipartition in granular mixtures. Some of the topics covered in this monograph include: Navier-Stokes transport coefficients for granular gases at moderate densities Long-wavelength instability in freely cooling flows Non-Newtonian transport properties in granular shear flows Energy nonequipartition in freely cooling granular mixtures Diffusion in strongly sheared granular mixtures Exact solutions to the Boltzmann equation for inelastic Maxwell models.Soft and Biological Matter,2213-1736Amorphous substancesComplex fluidsMathematical physicsFluid mechanicsFluidsPhysicsSoft and Granular Matter, Complex Fluids and Microfluidicshttps://scigraph.springernature.com/ontologies/product-market-codes/P25021Mathematical Applications in the Physical Scienceshttps://scigraph.springernature.com/ontologies/product-market-codes/M13120Engineering Fluid Dynamicshttps://scigraph.springernature.com/ontologies/product-market-codes/T15044Fluid- and Aerodynamicshttps://scigraph.springernature.com/ontologies/product-market-codes/P21026Numerical and Computational Physics, Simulationhttps://scigraph.springernature.com/ontologies/product-market-codes/P19021Amorphous substances.Complex fluids.Mathematical physics.Fluid mechanics.Fluids.Physics.Soft and Granular Matter, Complex Fluids and Microfluidics.Mathematical Applications in the Physical Sciences.Engineering Fluid Dynamics.Fluid- and Aerodynamics.Numerical and Computational Physics, Simulation.533.7Garzó Vicenteauthttp://id.loc.gov/vocabulary/relators/aut837273BOOK9910337882003321Granular Gaseous Flows2530727UNINA
