Theoretical analysis of power-law nanofluid across extended sheet with thermal-concentration slip and Soret/Dufour effect

Опубликована: Фев. 21, 2025

The present research explores the theoretical analysis of power-law nanofluid across extended sheet with thermal-concentration slip and Soret/Dufour effects. Physical problem is converted into non-linear differential equations via similar transformations. Keller box method has been utilized to solve problems. In framework, magnetic fields are integrated. Box approach apply on explanatory algebraic MATLAB software extract numerical graphical results. features such as temperature description, velocity mass distribution examined in relation different flow model variables. findings show that profile increases increasing variable while concentration rate decreased. It found heart transmission fluid increased Brownian motion Lewis variable. Present study useful for cooling process industrial mechanical systems.

Purpose The purpose of this reserach work aims to study the steady state laminar mixed convection flow electro magnetohydrodynamic (EMHD) nanofluid over a continuously moving plate is considered evaluate irreversible transportation fields inside boundary layer by traditional non-equilibrium thermodynamics variational approach. Design/methodology/approach Lagrangian forms principle are determined using trial polynomials and on including governing balance equations dual field method. Then, Euler–Lagrangian integral produce thicknesses momentum, temperature concentration. integration provides fields, skin friction, heat mass transfer rates as non-linear in terms dimensionless sources EMHD ( Q H ), Joule heating Ec Brownian motion N B thermophoresis T buoyancy force Ri ) nanoparticle concentration flux R study. Findings For asymptotic behavior results, appropriate ranges parameters, −0.3 ≤ 0.3, 0 0.1, 0.3 and, fixed values such Pr = 6.2, Sc 5, 0.2 X 1, considered. Some main findings shear, follows: aiding Lorentz > 0) increases friction transfer, but decreases transfer; nano particle parameter all transfers not at significant level. Originality/value In problem, significance effects Richardson number past stretching Riga focused discussed. This analysis can be applicable industrial extrusion, submerged bodies submarine hulls aerofoils.
