The focus of this article is to scrutinize the performances thermal radiation and superhydrophobicity on a free convection an electrically conducting fluid across upstanding microchannel affected by transverse magnetic field. plates were alternatively heated incorporated with suction/injection effect. approximate expressions formulated differential equations have been calculated. It interesting...

The intention of the ”von Kármán sodium” (VKS) experiment is to study the hydromagnetic dynamo effect in a highly turbulent and unconstrained flow. Much effort has been devoted to the optimization of the mean flow and the lateral boundary conditions in order to minimize the critical magnetic Reynolds number R m and hence the necessary motor power. The main focus of this paper lies on the role o...

Abstract In the Bénard convection governed nanofluid confined between two horizontal infinite free-free boundaries, effect of Hall current is investigated when it subjected to constant vertical magnetic field. The Buongiorno mathematical model for hydromagnetic flow with currents has been considered. Brownian motion effects and thermophoresis nanoparticles have included in energy equation. A re...

In this article I review the fundamentals of solar-dynamo theory. I describe both historical and contemporary observations of the solar magnetic field before outlining why it is believed that the solar field is maintained by a hydromagnetic dynamo. Having explained the basic dynamo process and applications of the theory to the Sun, I shall conclude by speculating on future directions for the th...
