چکیده
Flow simulation along human lung channel is one of the interests investigation in fluid dynamics. We have studied flow phenomena 11th generation as porous medium. The governing equations medium been solved numerically using finite difference scheme. effect different parameters are illustrated graphically. It observed that rate increases for increasing value pressure gradient, porosity effect, effective viscosity and dimensionless parameter . numerical experiment non-porous also studied. found compared with GANIT J.

An experimental study on hydraulic behavior of free-surface radial flow in coarse-grained porous media
The equations of fluids in porous media are very useful in designing the rockfill and diversion dams, gabions, breakwaters and ground water reserves. Researches have been showed that the Forchheimer equation is not sufficient for the analysis of hydraulic behavior of free-surface radial flows; because, in these flows, in addition to the hydraulic gradient and velocity, the variable of radius is...

Experimental Study of Nanofluids Flow in a Micromodel as Porous Medium
For better understanding the effect of nanofluid flow in a porous medium, a set of experiments were conducted on a horizontal glass micromodel for Al2O3-water nanofluids. To characterize the flow of nanofluids the same experiment was done by pure water. The glass micromodel was constructed by a photolithography techniqu...
متن کاملOn the signed porous medium flow
We prove that the signed porous medium equation can be regarded as limit of an optimal transport variational scheme, therefore extending the classical result for positive solutions of [13] and showing that an optimal transport approach is suited even for treating signed densities.
متن کاملA characteristic method for porous medium flow
We present an efficient and accurate characteristic method for the solution of the unsteady-state advection-diffusion transport equations, which arise in the mathematical models for flow and transport processes in porous media. The advantages of this method include symmetrizing the governing transport equation, treating boundary conditions naturally in the formulation, and conserving mass. More...
