Energy transfer in mixed convection unsteady magnetohydrodynamic (MHD) flow of an incompressible nanofluid inside a channel filled with saturated porous medium is investigated. The channel with non-uniform walls temperature is taken in a vertical direction under the influence of a transverse magnetic field. Based on the physical boundary conditions, three different flow situations are discussed...

secondary flow investigation could be regarded as an important issue in open channel flow, in spite of its lower quantity compared to the base flow in the water course. it should be given special consideration because of the influence on some hydraulic factors in open channel, specifically in compound channels. in compound channels' due to the difference in the flow velocity of the main ch...

An attempt is made for the first time to solve the quadratic and cubic model of magneto hydrodynamic Poiseuille flow of Phan-Thein-Tanner (PTT). A series solution of magneto hydrodynamic (MHD) flow is developed by using homotopy perturbation method (HPM). The results are presented graphically and the effects of non-dimensional parameters on the flow field are analyzed. The results reveal many i...

Keywords: MHD flow control Nonlinear boundary control Active mixing enhancement Distributed parameter systems a b s t r a c t A nonlinear Lyapunov-based boundary feedback control law is proposed for mixing enhancement in a 2D magnetohydrodynamic (MHD) channel flow, also known as Hartmann flow, which is electrically conducting, incompressible, and subject to an external transverse magnetic field...

An analysis of the magnetohydrodynamic (MHD) unsteady convective flow of a viscoelastic (second grade) fluid through a porous medium filled in a vertical channel is carried out. One of the porous plates of the channelthrough which the fluid is injected is subjected to a slip-flow condition and the other through which the fluid is sucked to a no-slip condition. The pressure gradient in the chann...

Unsteady flow of Casson fluid past through a vertical channel has been studied by some researchers due to its importance applications in science and technology. Therefore, the main purpose this paper is obtain exact solutions for unsteady free convection flows with effects magnetohydrodynamics (MHD) channel. This continued study from published article [18] additional (MHD). Dimensional governing...

An analysis of unsteady MHD flow of an electrically conducting visco-elastic fluid confined between two horizontal parallel non conducting plates in presence of a transverse magnetic field and Hall current is presented. The lower plate is a stretching sheet while the upper one is an oscillating porous plate, which is oscillating in its own plane. The motion of the fluid is produced by the stret...
