This paper proposes the P-1 radiation model for the calculation of low voltage arc plasma. The influence of both emission and self-absorption are taken into account in this model. Based on the couple of electric field, magnetic field, flow field and thermal field, a threedimensional arc chamber model is constructed and its radiation energy is calculated by the P-1 model with the spectrum divide...

steel slags are the by products of steel industries, which forms during reduction process of iron melting. the chemical composition of it changes depending to the melting procedure. its mineralogical composition also varies based on the cooling procedure. two different types of steel slag were used as absorbing bed for various concentrations of pb2+ ions in the form of lead chloride, and the co...

Phase 1, with electrical conductivity σ1, occupies the “bowtie” region of angle ±α, while phase 2, with conductivity σ2 σ1, occupies the remaining region. Deduce the approximate form of lines of current density J when a background electric field is applied along the symmetry axis of phase 1. What is the effective conductivity σ of the system, defined by the relation I = σΔφ between the total cu...

Plasma jets produced by direct-current (dc) non-transferred arc plasma torches, at the core of technologies ranging from spray coating to pyrolysis, present intricate dynamics due to the coupled interaction of fluid flow, thermal and electromagnetic phenomena. The flow dynamics from an arc discharge plasma jet are investigated using time-dependent three-dimensional simulations encompassing the ...
