Magnetic field approaches in dc thermal plasma modelling

Electromagnetic and thermal analysis of induction heating of billets by rotation in DC magnetic field

Induction heating is a widespread industrial technique and a subject of scientific research. The application fields of induction heating increase due to development of modern industrial technologies and advantages of the induction heating process. The development of traditional induction heating system applications for melting or through heating is mainly to increase power or production rates o...

New approaches in thermal plasma technology*

Thermal plasmas offer unique advantages for materials processing, such as high fluxes of heat and of reactant species. Recent developments have concentrated on improving control of these fluxes across the boundaries surrounding the thermal plasma. Secondary discharges (hybrid plasma generators) and pulse modulation of the plasma have been some of the approaches for this end. The use of such met...

Two-dimensional Fluid Model of DC and RF Plasma Discharges in Magnetic Field

The hydrodynamic equations of continuity and momentum for electrons and ions along with the electrostatic field equation are solved numerically using a self-consistent finite-element algorithm in the low-pressure, high frequency regime. The plasma formation over a flat plate is investigated for three different cases. The twodimensional numerical algorithm is first benchmarked with published lit...

The Magnetic Field Spectrum in a Plasma in Thermal Equilibrium in the Epoch of Primordial Nucleosynthesis

The low frequency magnetic field spectrum in the primordial plasma is of particular interest as a possible origin of magnetic fields in the universe (e.g., Tajima et al. 1992 and Cable and Tajima 1992). We derive the magnetic field spectrum in the primordial plasma, in particular, at the epoch of primordial nucleosynthesis. The pioneering study of Cable and Tajima (1992) of the electromagnetic ...
