ACOUSTIC WAVES IN A RAREFIED HIGH TEMPERATURE PLASMA
https://doi.org/10.26583/vestnik.2022.3
Abstract
The behavior of acoustic waves in a rarefied high-temperature plasma is studied, as an example of which the plasma of the solar corona is considered. The effects of thermal conductivity and heating/radiation losses are taken into account, and data on the temperature distribution of radiation intensity are used. An analytical representation in the form of interpolation by cubic splines is constructed for the radiation function. In the gas dynamics approximation, the dispersion relation for acoustic waves is obtained, from which the frequency, phase velocity and damping coefficient are found. In general, the superiority in dispersion and in damping of the thermal conductivity effect is shown. Heating and radiation losses manifest themselves at large wavelengths.
