Navier-Stokes-Fourier方程组的部分正则性

Partial regularity for the Navier-Stokes-Fourier system

Luisa Consiglieri

摘要:

本文研究了在Navier/Dirichlet边界条件下,粘性随温度变化的导热不可压缩牛顿流体与对流和粘性热源项耦合的非定常流动。对于每一个真弱解,即满足局部能量估计的弱解,证明了流体速度的部分正则性,其方法类似于Navier-Stokes方程组的适当弱解.最后,我们研究了空间和时间上的点集的性质,在这些点上真弱解可以是奇异的。

英文摘要:

This paper addresses a nonstationary flow of heat-conductive incompressible Newtonian fluid with temperature-dependent viscosity coupled with linear heat transfer with advection and a viscous heat source term, under Navier/Dirichlet boundary conditions. The partial regularity for the velocity of the fluid is proved to each proper weak solution, that is, for such weak solutions which satisfy some local energy estimates in a similar way to the suitable weak solutions of the Navier-Stokes system. Finally, we study the nature of the set of points in space and time upon which proper weak solutions could be singular.
