Squeezing flow of convectively heated fluid in porous medium with binary chemical reaction and activation energy

Abstract

In this communication, attention is paid to analyze theoretically the influence of the temperature-dependent binary chemical reaction for hydro-magnetic viscous fluid flow, flowing through the porous medium due to the squeezing phenomenon. For better understanding of variations in the processes of convective heat and mass transport, Arrhenius activation energy is also accounted. The equations governing the flow, heat, and mass are altered into non-linear differential system (ordinary differential equation) by means of suitable conversion methods. Efficient convergent technique is employed to compute resulting non-linear system. The solutions thus acquired are utilized to interrogate the behavior of the physical operating variables on flow velocity, fluid temperature, and fluid concentration. Coefficient of skin friction and rate of heat and mass transport are graphically elaborated. From the graphs, it is concluded that the temperature of fluid dominates against activation energy parameter [Formula: see text] and reaction parameter [Formula: see text]. However, an opposite trend is noted for concentration field. Moreover, temperature field and fluid concentration are incremented for dominant thermal and solutal Biot numbers, respectively. This analysis has the industrial processes which include engine cooling system, polymer industry, lubrication mechanisms, design of cooling and heating systems, molding of plastic sheets, designing porous surfaces to decrease drag, optimizing oil/gas production, in the domain of engineering (i.e. chemical, biomedical, geothermal etc.), chemical or nuclear system, cooling process in nuclear reaction, biochemical process, bimolecular reaction, and polymeric flows which is electrically conducted can be restrained and managed by exploiting the magnetic field. Encouraged by such physical situations, the proposed analysis is accomplished.

“…The Gou Tang hot spring is located in the Taikoo Basin vectorial axis, and the area of the hot spring is mainly composed of schist, metagranite and crystalline tuff of the Gai County Formation of the Liao he Group [18]. On the outer flanks of the hot spring area, gneisses, dacites and metagranites of the Da Shi Qiao Formation of the Liao he Group are exposed in order from the inside to the outside; gneisses, gneisses and hornblende of the Gao jia yu Formation of the Liao he Group; and metagranites, metavolcanic rocks, gneisses and dacites of the Lira yu Formation of the Liao he Group.…”

“…The new approximate analytical solution according to power series coefficients is used by Al-Saif and Jasim [17] to solve the similar problems. The flow on the porous medium is important in the such as thermal energy storage, nuclear reactors oil extraction, geothermal energy recovery and plasma studies [18]. The impacts of MHD on squeezing Casson flow across permeable medium was explored by Khan et al, [12].…”

Soret and Dufour effects on MHD squeezing flow of Jeffrey fluid in horizontal channel with thermal radiation

“…A solid matrix with interconnected voids is known as permeable medium. It is explored in industrial and natural cases, for instances groundwater flow, petroleum reservoir rocks, engine coolant system and aircraft wings in the permeable cavities [ 22 ]. Moreover, the hydrodynamic of magnetic field in the electrical conducted fluid, magnetohydrodynamics (MHD) is widely reviewed because of its applications in MHD pump and generator.…”
