报告题目: Inviscid Limit and Boundary Layer in Complex Fluids

报告人:   谢峰教授 （上海交通大学）

报告摘要：

In this talk we will review the classical Prandtl boundary layer double-scale asymptotic expansions in the analysis of structure of fluids with the high Reynolds number in a domain with boundaries. Inviscid limit can be regarded as a direct application of Prandtl boundary layer asymptotic expansions. Next, we consider the related inviscid limit and Prandtl boundary layer for several typical models arising from complex fluids, such as both incompressible and compressible Magneto-hydrodynamics equations, and compressible viscoelastic Equations etc.
