TEMPERATURE PROFILE OF A SPHERICAL PLASMA VOLUME, TAKING INTO ACCOUNT RECOMBINATION PROCESSES
Journal Title: Физика аэродисперсных систем - Year 2018, Vol 0, Issue 55
Abstract
physical-mathematical model of the heat balance of an open plasma environment with a central source in the presence of a negative temperature gradient and taking into account ionization- recombination processes has been developed. The ionization speed was calculated using the Dravin formula based on the Bethe-Born approximation; the recombination speed is described by the generalized Thompson theory. It is shown that a negative temperature gradient leads to an imbalance of ionization-recombination processes, as a result of which heat release due to recombination prevails in relation to heat losses due to ionization, which significantly affects the temperature profiles. The temperature profiles were calculated taking into account the ionization and recombination of iron for various parameters of the environment.
