摘要： A method of connecting three-dimensional structured meshes to form a conformal mesh, for solutions of flow problems, comprising:
- forming an interface by overlaying surfaces of two structured meshes;
- defining an interface set of mesh points in the interface;
- merging mesh points in the interface set that are within a predetermined distance of each other and projecting mesh points of one mesh in the interface that are within a predetermined distance of a line of the other mesh;
- generating an interface layer in the form of an unstructured mesh; and
- inserting a node at the centre of each hexahedra, and producing an unstructured layer of cells between the two structured meshes by joining the nodes to the mesh points of the interface layer.
This method ensures a thin unstructured layer with no hanging nodes.
摘要翻译：一种连接三维结构化网格以形成共形网格的方法，用于解决流动问题，包括： - 通过覆盖两个结构化网格的表面形成界面; - 定义接口中的网格点的接口集; - 将所述接口组中的网格点合并在彼此的预定距离内，并且在所述界面中的一个网格的网格点在另一个网格的线的预定距离内; - 以非结构化网格的形式生成界面层; 以及 - 将节点插入每个六面体的中心，并且通过将节点连接到界面层的网格点，在两个结构化网格之间产生非结构化的单元格层。这种方法确保了一个没有悬挂节点的薄非结构化层。

摘要： A casing treatment for a fan or compressor stage 10 of a gas turbine engine comprises circumferential grooves 16A, 16B, 16C, 16D and 16E which extend in a series disposed between the leading edges 20 and trailing edges 22 of blades 6 of a fan or compressor stage 10. The grooves 16 vary in depth d in order to optimise the stall margin of the fan or compressor stage 10 while preserving peak efficiency.
