摘要:

研究了三维有界区域上Brinkman-Forchheimer方程全局解的渐近稳定性.首先讨论了BrinkmanForchheimer方程对应的广义稳态椭圆方程解的存在唯一性,接着对这两种方程解之间的收敛性进行了讨论,最后分别在(L2(Ω))3和(H01(Ω))3中证明了Brinkman-Forchheimer方程强解关于初值和系数的连续依赖性.

In this paper,we study the asymptotic stability of the global solution of the three-dimensional Brinkman-Forchheimer equation on bounded domains.Firstly,we discuss the uniqueness of the solution of the generalized steady state elliptic equation corresponding to the Brinkman-Forchheimer equation.Then,we get the convergence of solutions between Brinkman-Forchheimer equation and its generalized steady state elliptic equation.Finally,we prove the continuous dependence of strong solution of Brinkman-Forchheimer equation on the initial value and the coefficient in(L2(Ω))3and(H10(Ω))3.
