Multiple Solutions for Slip Effects on Dissipative Magneto-Nanofluid Transport Phenomena in Porous Media: Stability Analysis
In the present paper, a numerical investigation of transport phenomena is considered in electrically-conducting nanofluid flow within a porous bed utilizing Buongiorno’s transport model and Runge-Kutta-Fehlberg fourth-fifth order method. Induced flow by non-isothermal stretching/shrinking sheet along with magnetic field impact, dissipation effect, and slip conditions at the surface are...
متن کاملDissolution Effects in Transport in Porous Media
The transport of reacting solutes in an equilibrium dissolution reaction leads to a moving boundary problem. Dependent on the boundary conditions we consider a two or three phase free boundary problem for a diiusion-convection and reaction process in a bounded domain. The system is driven out of equilibrium by a forced exchange of solutes with the exterior of the domain and is characterized by ...
متن کاملEffect of kaolinite, silica fines and pH on transport of polymer-modified zero valent iron nano-particles in heterogeneous porous media.
Polymer coatings on nano-sized remediation agents and subsurface heterogeneity will affect their transport, likely in a pH-dependent manner. The effect of pH on the aggregation of polymer-coated nanoscale zerovalent iron (nZVI) and its deposition onto sand and clay (kaolinite) surfaces was studied. nZVI coatings included a high molecular weight (90 kg/mol) strong polyanion, poly(methacrylic aci...
متن کاملTransport Property Estimation of Non-Uniform Porous Media
In this work a glass micromodel which its grains and pores are non-uniform in size, shape and distribution is considered as porous medium. A two-dimensional random network model of micromodel with non-uniform pores has been constructed. The non-uniformity of porous model is achieved by assigning parametric distribution functions to pores throat and pores length, which was measured using ima...
متن کاملREACTIVE TRANSPORT MODELLING OF DISSOLVED CO2 IN POROUS MEDIA Injection into and leakage from geological reservoirs
Reactive transport modelling of dissolved CO 2 in porous media iii Dedicated to my parents (late) and eldest sister. iv Reactive transport modelling of dissolved CO 2 in porous media v ABSTRACT The geological sequestration of carbon dioxide (CO 2) is seen as one of the options of mitigating the imbalance of greenhouse gas emissions and to avoid global warming. However, leakage of CO 2 from the ...
