Radiation hydrodynamics in astrophysics. (1987). Revista Mexicana De Astronomía Y Astrofísica, 14(1), 573-586. https://astronomia.unam.mx/journals/rmxaa/article/view/1987rmxaa..14..573i
Abstract
Starting from general covariant forms, the inertial and comoving-frame equations of radiation hydrodynamics are analyzed with a view to the relative importance of their different terms in two limit regimes of interest in astrophysics: the free-streaming regime, during radiative and fluid flow time-scales, and the static and dynamic diffusion regimes. Three dimensionless parameters are used: the ratio between material and radiation field energy density, the Boltzmann number, and the radiative Reynolds number. Both linear and nonlinear general solutions are discussed.Similar Articles
