in this paper, the combined effect of suspended (fine dust) particles and rotation on the onset of thermosolutal convection in an elastico-viscous fluid in a porous medium is studied. for the porous medium, the brinkman model is employed and rivlin-ericksen model is used to characterize viscoelastic fluid. by applying normal mode analysis method, the dispersion relation has been derived and sol...

An accurate and efficient simulator is developed for compressible flow porous media with wells. An Eulerian-Lagrangian localized adjoint method (ELLAM) is used to solve the transport partial differential equation for concentration, while a mixed finite element method (MFEM) is used to solve the pressure equation for the pressure and mass flow rate. The ELLAM-MFEM simulator symmetrizes the trans...

Development of additive manufacturing in last decade greatly improves tissue engineering. During the manufacturing of porous scaffold, simplified but functionally equivalent models are getting focused for practically reasons. Scaffolds can be classified into regular porous scaffolds and irregular porous scaffolds. Several methodologies are developed to design these scaffolds. A novel method is ...

Abstract Thermal convection in a fluid saturating an anisotropic porous medium local thermal nonequilibrium (LTNE) is investigated, with specific attention to the effect of variable viscosity on onset convection. Many fluids show remarkable dependence temperature that cannot be neglected. For this reason, we take into account whose decreases exponentially depth, according Straughan (Acta Mech. ...

In this paper, analysis for the propagation of general anisotropic media of finite thickness with two thermal relaxation times is studied. Expression of displacements, temperature, thermal stresses, and thermal gradient for most general anisotropic thermoelastic plates of finite thickness are obtained in the analysis. The calculation is then carried forward for slightly more specialized case of...

In this work the effects of heat generation on the modes of Yb:Glass double clad fiber laser were investigated. The thermal dispersion and thermally-induced birefringence were considered when the gain medium becomes an anisotropic medium. The results showed considerable modifications of laser modes profiles, in particular for transfer magnetic (TM) and transfer electric (TE) modes which their p...

the unsteady flow in porous medium of a viscous incompressible fluid bounded by two parallel porous plates is studied with heat transfer. a uniform and constant pressure gradient is applied in the axial direction whereas a uniform suction and injection are applied in the direction normal to the plates. the two plates are kept at constant and different temperatures and the viscous dissipation is...
