报告内容简介:

In this talk, we shall review our recent work on the mathematical theory of the Prandtl boundary layers. The well-posedness of the three dimensional Prandtl equations is studied under some constraint on its flow structure. It reveals that the classical Burgers equation plays an important role in determining this type of flow with special structure, which avoids the appearance of the complicated secondary flow in the three-dimensional Prandtl boundary layer. Meanwhile, we shall also address a recent progress on boundary layers in the non-isentropic compressible flows when both of viscosity and heat conduction coefficients go to zero. This is the joint work with Cheng-Jie Liu and Tong Yang.
