等熵Navier-Stokes方程组耗散测度值解的混合有限元有限体积格式的收敛性

Convergence of a mixed finite element finite volume scheme for the isentropic Navier-Stokes system via dissipative measure-valued solutions

Eduard Feireisl, Maria Lukacova-Medvidova

摘要:

研究了等熵Navier-Stokes方程组的混合有限元有限体积格式在绝热指数全范围内的收敛性。我们建立了适当的稳定性和一致性估计,并表明由数值解产生的Young测度代表了极限系统的耗散测度值解。特别地,利用最近建立的耗散测度值解类的弱{强}唯一性原理,证明了只要极限系统的强解存在,其数值解强收敛于该极限系统的强解.

英文摘要:

We study convergence of a mixed finite element finite volume numerical scheme for the isentropic Navier-Stokes system under the full range of the adiabatic exponent. We establish suitable stability and consistency estimates and show that the Young measure generated by numerical solutions represents a dissipative measure-valued solutions of the limit system. In particular, using the recently established weak{strong uniqueness principle in the class of dissipative measure-valued solutions we show that the numerical solutions converge strongly to a strong solutions of the limit system as long as the latter exists.
