论文摘要
回顾了带有伴随Euler方程的亚音速和跨音速速度的网格差异问题。通过检查最近衍生的分析伴随解决方案，可以表明解释是伴随解在壁上是单数。墙壁奇点是由后边缘处的伴随奇异性引起的，但不是以前猜想的方式。
The mesh divergence problem occurring at subsonic and transonic speeds with the adjoint Euler equations is reviewed. By examining a recently derived analytic adjoint solution, it is shown that the explanation is that the adjoint solution is singular at the wall. The wall singularity is caused by the adjoint singularity at the trailing edge, but not in the way it was previously conjectured.
