Effects of Magnetic Fields on Diffusion Flames

چکیده
Since the time of Faraday, several researchers have studied the effects of magnetic fields on flames. In his time, Faraday realized that the application of certain magnetic field configurations to a burning candle resulted an equatorial elongation of the combustion zone [1]. Recent researchers have confirmed what Faraday observed over a century earlier by showing that flames bent to escape magnetic fields of higher intensities [2-5]. In these studies, oxygen was shown to be attracted towards regions of stronger magnetic field, while nitrogen and other combustion products were pushed out towards a weaker field. This phenomenon was mainly attributed to the difference in magnetic susceptibility of gas species. Oxygen, being paramagnetic in nature, has a positive magnetic susceptibility while the rest of the combustion products are diamagnetic and have negative magnetic susceptibility. The magnetic force on gas species is governed by equation (1),

The Linear Instability of Astrophysical Flames in Magnetic Fields
Supernovae of Type Ia are used as standard candles for cosmological observations despite the as yet incomplete understanding of their explosion mechanism. In one model, these events are thought to result from subsonic burning in the core of an accreting Carbon/Oxygen white dwarf that is accelerated through flame wrinkling and flame instabilities. Many such white dwarfs have significant magnetic...

In this paper, we have investigated the effects of self-fields on gain in a helical wiggler free electron laser with axial magnetic field and ion-channel guiding. The self-electric and self-magnetic fields of a relativistic electron beam passing through a helical wiggler are analyzed. The electron trajectories and the small signal gain are derived. Numerical investigation is shown that for grou...
