Thermodynamics of Granular Media
نویسنده
چکیده
A thermodynamic formulation for moving granular material is proposed. The fluctuations due to the constant flux and dissipation of energy are controlled in a " granular " ensemble by a pressure ℘ (" compression ") which is conjugate to a contact volume (" contactopy "). The corresponding response function (" dissipativity ") describes how dissipation increases with ℘ and should serve to identify the fluidization transition and 1/f noise. In the granular ensemble one can consider the granular medium as a gas of elastically colliding particles and define a " granular " temperature and other standard thermodynamic quantities.

Dynamics of granular media
Granular media are very common in nature and technology but present, due to the inelasticity of the collisions between grains very astonishing collective phenomena. One of them is the spontaneous formation of clusters as observed in intergalactic dust. We will discuss the role of dissipation in these effects and show recent progress in the understanding of the deviation from classical thermodyn...
متن کاملThermodynamics and statistical mechanics of dense granular media.
By detailed molecular dynamics and Monte Carlo simulations of a model system we show that granular materials at rest can be described as thermodynamics systems. First, we show that granular packs can be characterized by few parameters, as much as fluids or solids. Then, in a second independent step, we demonstrate that these states can be described in terms of equilibrium distributions which co...
متن کاملThermodynamics of Extraction of Zn2+ from Sulfuric Acid Media with a Mixture of Dehpa and Mehpa
Thermodynamics of extraction of Zn2+ from sulfuric acid media contacting to a mixture of DEHPA and MEHPA diluted with 80 wt% aromatic-aliphatic kerosene with a constant DEHPA to MEHPA ratio is investigated at different acidities, concentrations and temperatures. As a result, the extraction reaction is found to be endothermic with a zinc distribution factor that increases with increasing of the ...
متن کاملMultilaminate Elastoplastic Model for Granular Media
A multilaminate based model capable of predicting the behavior of granular material on the basis of sliding mechanisms and elastic behavior of particles is presented. The capability of the model to predict the behavior of sand under arbitrary stress paths is examined. The influences of rotation of the direction of principal stress axes and induced anisotropy are included in a rational way witho...
متن کاملComparative potential of black tea leaves waste to granular activated carbon in adsorption of endocrine disrupting compounds from aqueous solution
The adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol A on locally available black tea leaves waste and granular activated carbon were investigated. The results obtained indicated that the kinetics of adsorption were pH, adsorbent dose, contact time and temperature dependent with equilibrium being reached at 20 ...
