In this article, a comprehensive analysis is performed for fly ash and paramagnetic ( ) a T nanoparticles with a hybrid base and micro polar fluid with momentum slip conditions over a stretching sheet. With the aid of the similarity transformation, the PDEs obtained are transmuted in the nonlinear ODE system, after which the numerical simulation is performed with the finite element method. The effect of physical parameters on velocity, micro rotation, and temperature are analyzed graphically. Results reveal that the velocity boundary layer thickness for fly ash nanoparticles is higher than paramagnetic and thermal conductivity of paramagnetic is higher than fly ash nanoparticles. The paramagnetic nanoparticles are, therefore, the best coolant. The comparison of the finite element method with previous researches is tabled and found in a good agreement.

The purpose of existing article is to analyze the effects of non-uniform heat source/sink and magnetic dipole in flow of ferromagnetic Maxwell liquid over a stretched sheet. Highlights of Brownian movement and thermophoresis are explored within the sight of magnetic dipole. Effects of thermal and concentration stratification are additionally considered. Apposite transformations are employed to obtain the nonlinear differential system. The procured nonlinear framework is locked in with the assistance of numerically by shooting technique. Velocity and temperature gradients are discussed and analyzed graphically.

Analysis of modified Fourier law in flow of ferromagnetic Powell–Eyring fluid considering two equal magnetic dipoles

et al. 2019

View full text Add to dashboard Cite

The target of the current study is to inspect theoretically 2D boundary layer flow of an Eyring–Powell ferromagnetic liquid over a flat plate. An external magnetic field due to two magnetic dipoles is applied. Modified Fourier law of heat flux model is employed. Constitutive relations for Eyring–Powell fluid are considered in the boundary layer flow analysis. Series results to the nonlinear formulation are derived and scrutinized by homotopic scheme. Characteristics of various parameters like magneto-thermomechanical (ferrohydrodynamic) interaction parameter, Prandtl number, and dimensionless thermal relaxation on temperature profile are displayed via graphs. It is noted that temperature field decays via thermal relaxation factor.
