报告摘要:  

The low Mach number limit of full compressible Navier-Stokes equations with large temperature variations is verifified rigorously in a three-dimensional bounded domain. Weighted uniform estimates of the solutions are derived in a time interval which is independent of the Mach number, in particular, for the high-order derivatives, when the initial data are well-prepared only in the sense of L^2-norm. It can be viewed as the fifirst result on the low Mach number limit of full Navier-Stokes equations with large temperature variations in bounded domains. 

The methods in the paper also apply to other flfluid models with large temperature variations.
