Краткое описание

As part of the radiation plasma dynamics, with account for radiation transfer, the problem is formulated dealing with plasma and gasdynamic processes in the flare of a capillary discharge with an evaporating electrode on the assumption of equality between the brightness temperature and the temperature of the outflowing plasma. A numerical solution of the system of equations is obtained in accordance with the nonstationary two-dimensional radiation magnetogasdynamic model that has been developed in the work and that is based on the method of splitting into physical processes and spatial directions. The results of calculations show that by the time t ~ 100 µs the brightness temperatures drop sharply from 10 to 3 kK and then change relatively little with time.
