We performed relativistic magnetohydrodynamic simulations of the hydrodynamic boosting mechanism for relativistic jets explored by Aloy & Rezzolla (2006) using the RAISHIN code. Simulation results show that the presence of a magnetic field changes the properties of the shock interface between the tenuous, overpressured jet (V z j ) flowing tangentially to a dense external medium. Magnetic field...

One of the key components regarding heat transfer and tritium inventories in deuterium-tritium nuclear fusion reactors is the (tritium) Breeding Blanket, called Test Blanket Module or TBM in ITER experiment. Several designs are going to be tested in ITER, one of those is the HCLL (Helium Cooled Lithium Lead) design. Before being tested, it is of major interest to predict in detail several flow ...

Background High fidelity 12-lead ECG is important for physiological monitoring during cardiovascular interventions. A dominant ECG R-wave is essential for synchronizing cardiac MRI. Obtaining the real ECG in MRI is challenging due to a superimposed Magneto-Hydro-Dynamic (MHD) voltage (VMHD) [1], & strong induced voltages from MRI switched gradients. Detecting acute ischemia by ST segment [2] is...

An analysis is discussed of the heat and mass transfer for micropolar nanofluid in presence natural convection from a spherical body with magneto-hydrodynamic (MHD) effects. The constant wall temperature boundary condition also studied. By employing proper similarity transformations, governing equations are converted into set partial differential (PDEs) used conditions, which can then be solved...

In the current investigation, numerical method (CVFEM) was selected to show impact of Lorentz force on transportation operate fluid (water with a mixture Fe3O4 and CuO). Adding source terms associated MHD (magneto-hydrodynamic) porous zone leads mathematical model utilizing vorticity formulation can make equations simplify. Not only viscous heating irreversibility but also permeable magnetic we...

We investigate the linear stability of a sinusoidal shear flow with an initially uniform streamwise magnetic field in framework incompressible magnetohydrodynamics (MHD) finite resistivity and viscosity. This is known to be unstable Kelvin-Helmholtz instability hydrodynamic case. The same true ideal MHD, where dissipation neglected, provided strength does not exceed critical threshold beyond wh...

The effects of chemical reaction, thermal stratification, Soret and Dufour numbers on magneto-hydrodynamic free convective heat and mass transfer of a viscous, incompressible,and electrically conducting fluid on a vertical stretching surface embedded in a saturated porous medium are presented. A similarity transform is used to reduce the governing partial differential equations into a syste...

A conjugate heat transfer for steady two-dimensional mixed convection with magnetic hydrodynamic (MHD) flow of an incompressible quiescent fluid over an unsteady thermal forming stretching sheet has been studied. A parameter, M, which is used to represent the dominance of the magnetic effect has been presented in governing equations. The similar transformation and an implicit finite-difference ...

The present work is concerned with exact solutions of Stokes second problem for magnetohydrodynamics (MHD) flow of a Burgers' fluid. The fluid over a flat plate is assumed to be electrically conducting in the presence of a uniform magnetic field applied in outward transverse direction to the flow. The equations governing the flow are modeled and then solved using the Laplace transform technique...

The molecular component of the Galaxy is comprised of turbulent, magnetized clouds, many of which are self-gravitating and form stars. To develop an understanding of how these clouds’ kinetic and structural evolution may depend on their level of turbulence, mean magnetization, and degree of self-gravity, we perform a survey of direct numerical MHD simulations in which three parameters are indep...
