Experimental Study on the Effect of Magnetic Field on Critical Heat Flux of Ferrofluid Flow Boiling in a Vertical Tube
In the present work, the critical heat flux measurements were performed for the subcooled flow boiling of pure water and magnetic nanofluids (i.e., water + 0.01 and 0.1 vol.% Fe3O4) in a vertical tube. The effect of applying an external magnetic field on the CHF variation was studied experimentally as well. The obtained results indicated that the subcooled flow boiling CHF in the vertical tub...
متن کاملMagnetic helicity and flux tube dynamics in the solar convection zone: Comparisons between observation and theory
[1] Magnetic helicity, a conserved topological parameter in ideal MHD systems, conditions close to which are realized in the solar plasma, is intimately connected to the creation and subsequent dynamics of magnetic flux tubes in the solar interior. It can therefore be used as a tool to probe such dynamics. In this paper we show how photospheric observations of magnetic helicity of isolated magn...

Injection of Magnetic Energy and Magnetic Helicity into the Solar Atmosphere by an Emerging Magnetic Flux Tube
We present a detailed investigation of the dynamical behavior of emerging magnetic flux using 3dimensional MHD numerical simulation. A magnetic flux tube with a lefthanded twist, initially placed below the photosphere, emerges into the solar atmosphere. This leads to a dynamical expansion of emerging field lines as well as an injection of magnetic energy and magnetic helicity into the atmospher...
متن کاملElectric/magnetic flux tube on the background of magnetic/electric field
One of the more fascinating aspects of quantum chromodynamics (QCD) is a quark confinement. The phenomenon of the confinement of quarks is connected with a hypothesized flux tube filled with the color electric field and stretched between quark and antiquark. This situation is in contrast with the electron and positron pair where the force lines in the whole space are spread. The confinement is ...
