Abstract
The paper deals with a numerical modeling of parameters of a water-vortex stabilized electric arc in the case when re-absorption of plasma radiation is taken into consideration. The radiation losses from the arc are involved through the net emission coefficient which is, in this model, composed of two parts: the first term accounts for the net emission radiation loss inside the arc while the second term mostly represents re-absorption of radiation at the colder arc boundary. It was proved that re-absorption of radiation influences arc parameters in a specific manner. The calculated characteristics are in reasonable agreement with experiments made on the water plasma torch operating at the Institute.
