Numerically optimized band boundaries of Planck mean absorption coefficients in air plasma
(IOP Publishing, 2017-08-02)
Radiation heat transfer plays an important role in the energy balance of plasma in an electric arc and its accurate prediction is essential for the development of new electrical devices. Unfortunately, a very complex ...
P1-approximation for radiative transfer: application to SF6 + Cu arc plasmas
(De Gruyter Open, 2014-12-01)
The objective of the paper consists of a theoretical prediction of radiative heat transfer in arc plasmas of SF6 (sulphur hexafluoride) with various admixtures of copper vapours. As a mathematical tool the P1-approximation ...
On the Selection of Integration Intervals for the Calculation of Mean Absorption Coefficients
(Springer US, 2015-10-18)
In radiation modeling of thermal plasmas non-grey models are applied where the radiative transport is described in several frequency bands (spectral intervals). Hereby mean absorption coefficients have to be calculated by ...
Influence of metal vapours on radiation characteristics of air arc plasmas
This paper deals with the evaluation of radiation properties of air arc plasma with various admixtures of Cu, Ag, and Fe, respectively. Under assumption of isothermal plasma cylinder, the net emission coefficients were ...
