我们提出了一种新技术来实现弯曲几何问题的稳定二维欧拉方程的实体壁边界条件。该技术将与高阶方法一起用于非结构化、直边单元网格。通过围绕物理几何而不是计算几何对流动进行建模，可以显着提高解决方案的质量。该技术不需要复杂的重建并且易于实现。举例说明了新方法的有效性。
We propose a new technique to implement solid wall boundary conditions for steady two-dimensional Euler equations for problems in curved geometries. The technique is to be used with high-order methods on unstructured, straight-sided element meshes. By modeling flow around a physical rather than computational geometry, significant improvement in quality of the solution is achieved. The technique does not require a complex reconstruction and is easy to implement. Examples are presented to demonstrate validity of the new approach.
