报告摘要: The Prandtl equation introduced by Prandtl in 1904 is a basic equation describling the behavior of the fluid near the boundary. In this talk, I will first introduce some recent results on the regularity, long-time behavior and boundary layer separation of the steady Prandtl equation. Then I will introduce the construction of the Tollmien-Schlichting waves in the subsonic regime, which play a key role during the early stage of the boundary layer transition.
