Hall Current Effects on MHD Convective Flow Past a Porous Plate with Thermal Radiation, Chemical Reaction and Heat Generation/Absorption
In this paper an attempt is made to study the chemical reaction and combined buoyancy effects of thermal and mass diffusion on MHD convective flow along an infinite vertical porous plate in the presence of Hall current with variable suction and heat generation. A uniform magnetic field is applied in a direction normal to the porous plate. The equations governing the fluid flow are solved using the perturbation technique and the expressions for the velocity, the temperature and the concentration distributions have been obtained. Dimensionless velocity, temperature and concentration profiles are displayed graphically for different values of the parameters entering into the problem like Prandtl number Pr, Hartmann number M, Grashof number G, modified Grash of number Gc, Hall parameter m, Heat source parameter χ, Schmidt number Sc, and Chemical reaction parameter ξ. The Skin-friction coefficient, rate of heat transfer and mass transfer at the plate have been obtained and also discussed through tables. It has been observed that an increase in the Prandtl number leads to a decrease in the primary and secondary velocities, and also a decrease in the temperature. The primary and secondary velocities decrease with increase in the Chemical reaction parameter or Magnetic field parameter
MHD Heat and Mass Transfer Steady Flow of a Convective Fluid Through a Porous Plate in The Presence of Diffusion Thermo and Aligned Magnetic Field
In the presence of a diffusion thermal and coupled magnet field effect, this manuscript seeks continuous free convective motion by a viscous, incompressible fluid that conducts electrically past a sloping platform via a porous medium. The free flow speed may be compatible with the exponentially tiny disrupting law. Two-term harmonic and non-harmonic functions solve dimensional-less control equations analytically. Detailed graphs are used to determine the budgets for tempo, temperature, and concentration for various limit calculations. Also, the numbers of Nusselt and Sherwood are given and evaluated with the graphs. Its sketches illustrate that the velocity profiles get reduced by the increase of aligned magnetic field parameter (α) and inclined angle parameter (ξ). Temperature profile is accelerated by rising heat absorption, Dufour number and concentration distribution is decelerated by enhancing the chemical reaction and Schmidt number. Heat and mass transfer frequently occurs in chemically processed industries, distribution of temperature and moisture over agricultural fields, dispersion of fog and environment pollution and polymer production. Free convection flow of coupled heat and mass transfer occurs due to the temperature and concentration differences in the fluid as a result of driving forces. For example, in atmospheric flows, thermal convection resulting from heating of the earth by sunlight is affected differences in water vapour concentration
Inclined surface mixed convection flow of viscous fluid with porous medium and Soret effects
The combined heat and mass transfer phenomenon is a significant aspect of engineering and industrial processes. This phenomenon finds applications in various areas such as air conditioning, cooling and heating control of electronic devices, reactors, chemical systems, and emission processes. This research model focuses on the analysis of mixed convection flow of a viscous fluid with heat and mass transfer on an inclined surface with porous medium characteristics. The study also considers external heat transfer effects, radiation, Soret influence, and chemical reactions. A perturbation solution is derived in closed form, and the impact of various parameters on the thermal behavior is investigated. A comparative analysis of the heating and cooling regimes in plate flow is conducted, revealing a reduction in velocity in the heated plate regime with changes in the permeability parameter and an increase in concentration phase due to the Soret number
Thermal impact of hybrid nanofluid due to inclined oscillatory porous surface with thermo-diffusion features
Owing to improved thermal efficiencies of hybrid nanomaterials, various applications of such tiny particles are claimed in enhancing thermal impact in heat transfer phenomenon, improving the efficiencies of solar collectors, thermal management systems and different industrial processes. Following to such motivations in mind, this research communicates the thermal impact of hybrid nanofluid with utilization of different nanoparticles due to porous infinite plate. The characterization of hybrid nanoparticles is observed with interaction of copper (Cu), aluminium oxide (Al2O3), titanium oxide (TiO2) with water base fluid The phenomenon is supported with thermal radiation phenomenon. The porous medium with uniform permeability is considered within flow regime. The onset of chemical reaction is attributed in concentration equations. The closed form solution is obtained via analytical procedure. The thermal assessment of nanoparticles in flow regime with effect of different parameters is considered. The comparative thermal observations are reported for pure nanofluid and with different nanoparticles
