在目前的工作中，一个开源的高阶声传播的快速耦合接口。该接口在两个开源代码OpenFOAM和Nektar++之间实现。耦合接口上的2D圆柱的情况下，显示出非常好的协议与解析解，并证明其高效率相比，传统的文件为基础的耦合方法进行了验证。一个更现实的杆翼型尾流干扰的情况下，也进行了研究，以验证该方法在更复杂的配置的适用性。虽然接口实现只实现了所选择的两个开源代码，其适应其他类似的求解器/包预计是直截了当的。
In the present work, an open-source fast coupling interface for high-order acoustic propagation is presented. This interface is implemented between two open-source codes, OpenFOAM and Nektar++. The coupling interface is validated on a 2D cylinder case showing a very good agreement with the analytical solution and demonstrating its high efficiency as compared to traditional file-based coupled methods. A more realistic rod-airfoil wake interaction case is also studied to verify the applicability of the methodology in more complex configurations. Although the interface implementation is only realised for the chosen two open-source codes, its adaptation to other similar solvers/packages is expected to be straightforward.
