Spatial decay estimates for the Brinkman-Forchheimer fluid interfacing with a Darcy fluid in porous medium
摘要:
研究了多孔介质中一类相互作用的Brinkman-Forchheimer流与Darcy流的空间衰减估计.首先定义一个加权的能量表达式,然后借助一些有用的引理推导出该能量表达式所满足的微分不等式,最后得到解的空间衰减估计结果.
The Spatial decay estimates for the Brinkman-Forchheimer fluid interfacing with a Darcy fluid in porous medium is studied.Firstly,the weighted energy expression is defined.Then,with the help of some useful lemmas,the differential inequality satisfied by the energy expression is derived.Finally,the result of the spatial decay estimates of the solution is obtained.
