We are interested in studying the stationary second grade fluid model in a bounded domain in . To approximate the solution of the continuous model, we propose a fully decoupled numerical scheme based on a splitting method combined with the use of the operator. This approach allows the complete decoupling of the three variables: velocity, pressure and vorticity. Each variable is computed using an iterative procedure, with the pressure step involving a simple -projection.

稳态二级流体模型高效方案的收敛性分析


我们有兴趣研究有界域中的平稳二级流体模型。为了近似连续模型的解，我们提出了一种基于分裂方法并结合算子使用的完全解耦数值方案。这种方法可以完全解耦三个变量：速度、压力和涡度。每个变量都是使用迭代过程计算的，其中压力步骤涉及简单的投影。
