This thesis is concerned with the global solvability and the precise description of large time behavior of global solutions to the compressible viscous and heat-conducting ideal polytropic gases in a bounded concentric annular domain with radiation and temperature dependent viscosity.For the case that the transport coefficients are smooth functions of temperature,a unique global-in-time spherically or cylindrically symmetric classical solution to the above initial-boundary value problem is shown to exist and decay into a constant equilibrium state at exponential rate as the time variable tends to infinity.In our results,the initial data can be large if the adiabatic exponent is sufficiently close to 1. |
