Photospheric magnetic vortex structures [PDF]

, 2011
Using direct numerical magneto-hydrodynamic (MHD) simulations, we demonstrate the evidence of two physically different types of vortex motions in the solar photosphere.

Generalized MHD equations

Journal of Differential Equations, 2003
The paper deals with the \(d\)-dimensional generalized MHD (GMHD) equations \[ \begin{aligned} &\partial_{t}u + u\cdot \nabla u =-\nabla P + b \cdot \nabla b - \nu (-\Delta)^{\alpha} u,\\ &\partial_{t}b + u \cdot \nabla b= b \cdot \nabla u - \eta (-\Delta)^{\beta} b, \end{aligned} \] where the fractional power \((-\Delta)^{\alpha}\) is defined via a ...

Computational Role in Thermal Engineering and Chemical Analytics During the Rotating Disk of Generalized Williamson Viscosity and Thermal Conductivity

Advanced Physics Research, EarlyView.
The schematic diagram shows the flow configuration of the model. The swirling flow of shear‐thinning materials is significantly investigated under the influence of mixed convection. In addition, heat and mass transfer flow characteristics along with gyrotactic microorganisms is also investigated. ABSTRACT Thermal conductivity, temperature gradient, and

von Kármán self-preservation hypothesis for magnetohydrodynamic turbulence and its consequences for universality [PDF]

, 2012
We argue that the hypothesis of preservation of shape of dimensionless second- and third-order correlations during decay of incompressible homogeneous magnetohydrodynamic (MHD) turbulence requires, in general, at least two independent similarity length ...

Multifluid equations for MHD

Journal of Geophysical Research: Space Physics
A set of MHD equations is developed for multiple ion species in the limit of small Larmor radius. The derivation proceeds to explicitly calculate the Lorentz force resulting from the small ion drift velocities. The net effect is that in this limit all the ions move perpendicular to the magnetic field with the same E×B speed, but are free-streaming ...

Optimized Wavy Thermal Radiative Analysis of Electrochemically Ternary Hybrid Nanomaterials Affected by an Induced Magnetic Force: An ANN‐Based Levenberg–Marquardt Backpropagation Approach

Advanced Physics Research, EarlyView.
This diagram illustrates the wavy flow configuration of the model in a Cartesian coordinate system. It represents the heat and mass transfer characteristics of ternary hybrid nanofluids over a vertically wavy surface in the presence of an induced magnetic field and double‐diffusive mixed convection.
