摘要:
In this paper, a Stabilized Crank-Nicolson LeapFrog (SCNLF) method for the non-stationary Navier-Stokes/Darcy model is presented and analyzed. Initially, we decompose the coupling model into Navier-Stokes and Darcy equations. The spatial discretization by stabilized finite element method and the temporal discretization by CNLF method give a second-order partitioned method. Stability and error estimate of the numerical method are given. Finally, some numerical tests are presented to justify the theoretical analysis. (C) 2021 Elsevier B.V. All rights reserved.
