Mathematical Modeling of Flow in a Granular Permeable Bed Channel
In this research, a two-dimensional mathematical model using turbulence model was developed in a rectangular channel with granular permeable bed. Finite volume method was used for numerical solution of governing equations. The equations considered are discretized using Hybrid difference scheme while applying SIMPLE algorithm to correct velocity components in the continuity equation. In the dev...
متن کاملErosion dynamics of a wet granular medium.
Liquid may give strong cohesion properties to a granular medium, and confer a solidlike behavior. We study the erosion of a fixed circular aggregate of wet granular matter subjected to a flow of dry grains inside a half-filled rotating drum. During the rotation, the dry grains flow around the fixed obstacle. We show that its diameter decreases linearly with time for low liquid content, as wet g...
متن کاملMathematical modeling of chemically reactive pollutants in indoor air.
W1lliam W Nazaro!f and Glen R. Cass• Environmental Engineering Science California Institute of Technology Pasadena, CA 91125 A general mathematical model is presented for predicting the concentrations of chemically-reactive compounds in indoor air. The model accounts for the effects of ventilation, filtration, heterogeneous removal, direct emission, and photolytic and thermal chemical reactions...
متن کاملDivergence of Viscosity in Jammed Granular Materials: A Theoretical Approach.
A theory for jammed granular materials is developed with the aid of a nonequilibrium steady-state distribution function. The approximate nonequilibrium steady-state distribution function is explicitly given in the weak dissipation regime by means of the relaxation time. The theory quantitatively agrees with the results of the molecular dynamics simulation on the critical behavior of the viscosi...
متن کاملMathematical Modeling of Fiber Reinforced Structures by Homogenization
We present another proof of a study of Bellieud and Bouchitté that we expect to be more suitable to treat more general geometrical and physical cases. We consider the homogenization of the quasi-linear elliptic problem − div σε = f, σε = aε |∇uε|∇uε on Ω uε = u0 on Γ0 σε · n = g on Γ1 where Ω is a bounded cylindrical open subset of R and 1 < p < +∞. The fibers occupy a set of thin parallel cyli...
