Solar Nebula Magnetohydrodynamics [PDF]
, 2000 The dynamical state of the solar nebula depends critically upon whether or not the gas is magnetically coupled. The presence of a subthermal field will cause laminar flow to break down into turbulence. Magnetic coupling, in turn, depends upon the ionization fraction of the gas.

Engineering Reports, Volume 7, Issue 4, April 2025.This study investigated the dissipative effects on time‐dependent Casson nanofluid motion over a cone, considering variable heat source/absorption and higher‐order reacting species. Water ethylene glycol was employed as the Casson base fluid. The proposed model has broad applicability across various scientific, engineering, and technological domains ...

Engineering Reports, Volume 7, Issue 4, April 2025.The present study investigates heat and mass transfer of electrically conducting second‐grade hybrid nanofluid flow over a stretching cylinder in the presence of nonuniform heat sources and nonlinear thermal radiation. The application of such hybrid nanofluid in second‐grade fluid flow can significantly enhance thermal conductivity and heat transfer ...

Existence of weak solutions to the three-dimensional density-dependent generalized incompressible magnetohydrodynamic flows [PDF]
arXiv, 2011 In this paper we consider the equations of the unsteady viscous, incompressible, and heat conducting magnetohydrodynamic flows in a bounded three-dimensional domain with Lipschitz boundary. By an approximation scheme and a weak convergence method, the existence of a weak solution to the three-dimensional density dependent generalized incompressible ...

On some large global solutions for the compressible magnetohydrodynamic system [PDF]
arXiv, 2018 In this paper we consider the global well-posedness of compressible magnetohydrodynamic system in $\R^d$ with $d\geq2$, in the framework of the critical Besov spaces. We can show that if the initial data, the shear viscosity and the magnetic diffusion coefficient are small comparing with the volume viscosity, then compressible magnetohydrodynamic ...

A well-posedness theory in Sobolev spaces for the stochastic magnetohydrodynamic equations in the whole space [PDF]
arXiv, 2020 We prove the existence of a mild solution to the three dimensional incompressible stochastic magnetohydrodynamic equations in the whole space with the initial data which belong to the Sobolev spaces.
