Analytical investigation of MHD blood flow in a porous inclined stenotic artery under the influence of the inclined magnetic field has been done. Blood is considered as an electrically conducting Newtonian fluid. The physics of the problem is described by the usual MHD equations along with appropriate boundary conditions. The flow governing equations are finally transformed to nonhomogeneous se...

‎the problem of two-phase mhd boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. the effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. the governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...

We investigate MHD-Couette--Shercliff flows driven by lateral wall motion with turbulent transitions observed only at supercritical Re. Linearly, the Tollmien--Schlichting (TS) wave instability was isolated each for friction parameter H $\ensuremath{\gtrsim}$ 300 in MHD-Couette flow, and 1000 Shercliff flow. At low H, linear nonlinear growth led to saturation a traveling wave, where waves conjo...

Abstract Some plasma propulsion concepts rely on a strong magnetic field to guide the plasma flow through the thruster nozzle. The question then arises of how the magnetically confined plasma can detach from the spacecraft. This work presents an MHD detachment scenario in which the plasma flow stretches the magnetic field lines to infinity. Detachment takes place after the energy density of the...

در ژنراتور mhd گازهای یونیزه شده احتراق از کانالی عبور داده می شود و مستقیما بر اثر وجود میدان مغناطیسی خارج جریان برق تولید میشود . بنا براین برخلاف سیستم های معمولی تبدیل انرژی قطعات ژنراتور mhd بدون حرکت بوده بنابراین از این نظر مزیت بسیار دارد . ژنراتور mhd دارای بازده حرارتی نزدیک به 55 درصد میباشد و در ظرفهای مرکب واحد تولید انرژی در نیروگاه ها ممکن است بکار برده شود . ژنراتورmhd امروزه ...

We consider the three-dimensional incompressible free-boundary magnetohydrodynamics (MHD) equations in a bounded domain with surface tension on boundary. establish priori estimate for solutions Lagrangian coordinates $H^{3.5}$ regularity. To best of our knowledge, this is first result focusing ideal MHD tension. It worth pointing out that $1/2$-extra spatial regularity flow map $\eta$ no longer...

A semi-analytical investigation has been carried out to analyze unsteady MHD second-grade flow under the Dual-Phase-Lag (DPL) heat and mass transfer model in a vertical microchannel filled with porous material. Diffusion thermo (Dufour) effects and homogenous chemical reaction are considered as well. The governing partial differential equations are solved by using the Laplace transform method w...
