无粘伴随解在固体壁面处的奇异性与网格发散
Singularity and Mesh Divergence of Inviscid Adjoint Solutions at Solid Walls
AI总结：
本文研究了伴随Euler方程在亚音速和跨音速下的网格发散问题，通过分析解析伴随解，发现该问题源于壁面奇异性，且该奇异性由后缘伴随奇异性以不同于以往推测的方式引起。
摘要：
本文回顾了伴随 Euler 方程在亚音速和跨音速速度下出现的网格发散问题。通过检验最近推导的解析伴随解，表明其解释是伴随解在壁面处具有奇异性。该壁面奇异性由后缘处的伴随奇异性引起，但并非以先前推测的方式产生。
英文摘要：
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.
