New exact solutions for unsteady magnetohydrodynamic MHD flows of an Oldroyd-B fluid have been derived. The Oldroyd-B fluid saturates the porous space. Two different flow cases have been considered. The analytical expressions for velocity and shear stress fields have been obtained by using Laplace transform technique. The corresponding solutions for hydrodynamic OldroydB fluid in a nonporous sp...

Abstract The solar atmosphere is known to be replete with magneto-hydrodynamic wave modes, and there has been significant investment in understanding how these waves propagate through the Sun’s deposit their energy into plasma. waves’ journey made interesting by vertical variation plasma quantities that define atmosphere. In addition this large-scale inhomogeneity, a wealth of fine-scale struct...

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...

There is abundant observational evidence that the energization of plasma particles in space is correlated with an enhanced activity of large-scale MHD waves. Since these waves cannot interact with particles, we need to find ways for these MHD waves to transport energy in the dissipation range formed by small-scale or high-frequency waves, which are able to interact with particles. In this paper...

We present three-dimensional magnetohydrodynamic (MHD) simulations of superbubbles, to study the importance of MHD effects in the interpretation of images from recent surveys of the Galactic plane. These simulations focus mainly on atmospheres defined by an exponential density distribution and the Dickey & Lockman (1990) density distribution. In each case, the magnetic field is parallel to the ...
