Radiative Heat Transfer in SF6 Arc Plasma

conference paper

en

Radiation emission and absorption in SF6 arc plasmas are important energy transfer processes. Exact calculations, though possible in principle are usually impossible in practice because of the need to treat large number of spectral lines and also continuum radiation in the whole spectrum range. We have used approximate method of partial characteristics to evaluate radiation intensities, radiation fluxes and divergence of radiation fluxes for SF6 arc plasma with cylindrical symmetry. We have treaed arcs with various temperature and pressure distributions. Conclusions have been made concerning validity and utilization of the method of partial characteristics in general gas dynamics problems.
