Mathematical Modelling of Radiative Heat Transfer Using Partial Characteristics

Popis výsledku v původním jazyce

Electric arcs are characterized among others by intensive radiation and high temperature conduction path made of highly ionised gas. The role of radiation rises rapidly with increasing pressure and the arc current. At higher temperatures and pressures, radiative heat transfer starts to determine the formation of the arc burning regime and all its thermal and electrical characteristics. Difficulties in investigating radiative heat transfer in real systems are related to the nonlinear structure of the equations that describe the phenomenon and to the strong dependence of the radiation field characteristics on the radiation frequency and properties of the arc plasma. The method of partial characteristics can be used as a good mathematical tool for mathematical modelling of the radiative heat transfer in the arc plasmas. In the present paper, principles of this method are given together with its application to the plasma radiation of the arc burning in sulphur hexafluoride (SF6).
