Heat and mass transfer on MHD squeezing flow of Jeffrey nanofluid in horizontal channel through permeable medium

Abstract

The heat and mass transfer on time dependent hydrodynamic squeeze flow of Jeffrey nanofluid across two plates over permeable medium in the slip condition with heat generation/absorption, thermal radiation and chemical reaction are investigated. The impacts of Brownian motion and thermophoresis is examined in the Buongiorno’s nanofluid model. Conversion of the governing partial differential equations to the ordinary differential equations is conducted via similarity transformation. The dimensionless equations are solved by imposing numerical method of Keller-box. The outputs are compared with previous reported works in the journals for the validation of the present outputs and found in proper agreement. The behavior of velocity, temperature, and nanoparticles concentration profiles by varying the pertinent parameters are examined. Findings portray that the acceleration of the velocity profile and the wall shear stress is due to the squeezing of plates. Furthermore, the velocity, temperature and concentration profile decline with boost in Hartmann number and ratio of relaxation to retardation times. It is discovered that the rate of heat transfer and temperature profile increase when viscous dissipation, thermophoresis and heat source/sink rises. In contrast, the increment of thermal radiation reduces the temperature and enhances the heat transfer rate. Besides, the mass transfer rate decelerates for increasing Brownian motion in nanofluid, while it elevates when chemical reaction and thermophoresis increases.

Analysis of Inertia Effect on Axisymmetric Squeeze Flow of Slightly Viscoelastic Fluid Film between Two Disks by Recursive Approach

“…Here, we are computing the solution of the third-order problem ( 26)-( 28) corresponding to homogeneous boundary conditions (30) for the velocity field. Putting the first-and second-order solution into Equations ( 26)-( 28), the resulting equations are transformed into the stream function by the relation u (3) = − 1 r ∂ψ (3) ∂z , w (3) = 1 r ∂ψ (3) ∂r , and eliminating the resulting pressure, one can reach the following form:…”

“…Shankar and Naduvinamani numerically simulated features of the Cattaneo-Christov heat and mass fluxes in an unsteady two-dimensional squeeze flow of a magnetohydrodynamic (MHD) Casson fluid between two parallel plates with radiation and Joule dissipation effects under the impact of time-dependent homogenous first-order chemical reactions [28]. Chemical reactions and viscous dissipation on the hydromagnetic squeeze flow of Jeffrey fluid across two plates over a porous medium in slip conditions with the effects of heat generation, absorption, thermal radiation and chemical reaction were examined by Azlina [29][30][31][32] using the Keller-Box technique. Hameedullah et al [33,34] examined the analytical result of the creeping flow of slightly viscoelastic fluid through a porous slit with constant reabsorption using the recursive approach.…”

Numerical Comparison of Cu and Al\(_2\) O\(_3\) Nanoparticles in an MHD Water-based Nanofluid

“…Irfan et al [13] analysed the impact of time-dependent viscosity, thermal conductivity, surface stretching, and wall temperature on MHD nanofluid flow thermophysical properties. Noor et al [14] studied the MHD flow of Jeffrey nanofluids, emphasising volume fraction effects rather than nanoparticle material. Results showed that increasing magnetic field intensity slowed down the flow, consistent with previous studies.…”

Thermal efficiency of flat plate solar collector with TiO2-based nanofluid: synergistic effect of size and facet orientation

“…The nanofluid has been prepared by adding nanoparticles into the traditional thermal transfer fluids to improve its thermal properties and, hence, the efficiency of the overall collector. The nanofluids have some improved parameters in comparison to bulk counterparts, like high thermal conductivity, optical extinction coefficient, heat transfer coefficient, electrical conductivity, density, and viscosity [13][14][15][16][17]. Therefore, in the recent years, application of nanofluids in solar collectors has attracted growing interest.…”
