Non-Equilibrium Transport

چکیده
Suppose we flow through an adsorption or chromatograph column so fast that the adsorption is not at equilibrium at a given point in the column. This departure from equilibrium could be either due to diffusion resistance within the porous particles of the column or due to kinetic limitation of the adsorption process. Alternatively, you may wish to separate different size macromolecules by the difference in the diffusivity of the macromolecules. This is commonly known as size-exclusion chromatography. Another case is measurement of the saturation of a nonaqueous phase by partitioning tracers. We will first derive the analytical solution for the general case and then derive the mass transfer coefficients for specific cases.

Slip flow in porous micro-tubes under local thermal non-equilibrium conditions
In the present work, forced convection heat transfer of slip flow in porous micro-tubes with local thermal non-equilibrium between the gas and the solid matrix is investigated numerically. For this purpose, the flow is considered hydrodynamically developed but thermally developing. The Darcy-Brinkman-Forchheimer model in conjunction with separate energy equations for the gas and the solid matri...

Graphene based optical devices are highly recommended and interested for integrated optical circuits. As a main component of an optical link, a photodetector based on graphene nano-ribbons is proposed and studied. A quantum transport model is presented for simulation of a graphene nano-ribbon (GNR) -based photo-transistor based on non-equilibrium Green’s function method. In the proposed model a...
متن کاملModelling of Sediment Transport in Beris Fishery Port
In this paper, the large amount of sedimentation and the resultant shoreline advancements at the breakwaters of Beris Fishery Port are studied. A series of numerical modeling of waves, sediment transport, and shoreline changes were conducted to predict the complicated equilibrium shoreline. The outputs show that the nearshore directions of wave components are not perpendicular to the coast whic...

Price policies are one of the most permissive policies in Iranian economic for controlling energy carrier's consumption. In addition, the non-price policies such as energy efficiency improvement are effective for controlling energy carrier's consumption. This paper assesses the economic impacts of energy efficiency improvement (in gasoline, gasoil and electric) as a non-price policy. For the pu...
