Properties of interplanetary magnetic sector boundaries based on electron heat-flux flow directions

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...

Correlation between Occurrence of Pearl Pulsations and Interplanetary Magnetic Field Sector Boundaries

A significant correlation between the occurrence of pearl pulsations at College, Alaska, and interplanetary magnetic field sector boundaries has been observed. Pearl pulsation data published by the Geophysical Institute, University of Alaska, and sector data published by Wilcox and Ness have been used to show the following: pearl pulsations are more likely to occur on the day a sector boundary ...

Hamiltonian magnetic reconnection with parallel electron heat flux dynamics

The Effect of Linear Change of Tube Diameter on Subcooled Flow Boiling and Critical Heat Flux

One of the major industry problems is the flow boiling, where reaching to the critical heat flux (CHF) condition can lead to a temperature jump and damage of the systems. In the present study, the effects of a uniform change in tube diameter on subcooled flow boiling and CHF was numerically investigated. The Euler-Euler model was used to investigate the relationship between the two liquid and v...

Conductive electron heat flow along an inhomogeneous magnetic field

In this work a general closure for the conductive electron heat flux parallel to an inhomogeneous magnetic field is derived and examined. Free-streaming and collisional effects are present in the drift kinetic equation which is solved using an expansion of eigenfunctions of the bounce-averaged, pitch-angle scattering operator. For bounce times short compared to transit and collision times, the ...
