Effects of Magnetic Field and Nonlinear Temperature Profile on Marangoni Convection in Micropolar Fluid
The combined effects of a uniform vertical magnetic field and a nonuniform basic temperature profile on the onset of steady Marangoni convection in a horizontal layer of micropolar fluid are studied. The closed-form expression for the Marangoni number M for the onset of convection, valid for polynomial-type basic temperature profiles upto a third order, is obtained by the use of the single-term...
متن کاملEffect of non-uniform Magnetic Field on Non-Newtonian Fluid Separation in a Diffuser
The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...
متن کاملEffect of Uniform Magnetic Field on Rayleigh Bènard Marangoni Convection in a Relatively Hotter or Cooler Layer of Liquid
The effect of uniform vertical magnetic field on the onset of steady Rayleigh-Bènard-Marangoni convection in a relatively hotter or cooler layer of electrically conducting liquid is studied theoretically by means of modified linear stability analysis. The top surface of the layer is non-deformable free where surface tension gradients arise on account of variation of temperature, and the bottom ...
متن کاملEffect of a magnetic field on the onset of Marangoni convection in a micropolar fluid
With the presence of a uniform vertical magnetic field and suspended particles, thermocapillary instability in a horizontal liquid layer is investigated. The resulting eigenvalue is solved by the Galerkin technique for various basic temperature gradients. It is found that the presence of magnetic field always has a stability effect of increasing the critical Marangoni number. Keywords—Marangoni...
متن کاملEffect of Variable Thermal Conductivity and the Inclined Magnetic Field on MHD Plane Poiseuille Flow in a Porous Channel with Non-Uniform Plate Temperature
The aim of this paper is to investigate the effect of the variable thermal conductivity and the inclined uniform magnetic field on the plane Poiseuille flow of viscous incompressible electrically conducting fluid between two porous plates Joule heating in the presence of a constant pressure gradient through non-uniform plate temperature. It is assumed that the fluid injection occurs at lower pl...
