Abstract:

An analytical study was made to determine the properties of arc discharges heated by combinations of induction and d.c. electromagnetic fields. Induction power is supplied to the discharge by a solenoidal coil whose axis of symmetry is aligned with the applied d.c. electric field. A numerical technique is used to simultaneously solve a set of linear differential equations which include Maxwells field equations, the single fluid energy equation, the momentum balance equation, Ohms law, and the radiation diffusion equation. A number of reasonable assumptions are made to obtain the final set of equations for programming. These assumptions restrict the calculations to azimuthally symmetric plasmas with axial gradients only in static pressure. In addition, the radiant energy flux is assumed to be isotropic within the plasma. Modified author abstract
