讲座题目: Persistence of the steady planar normal shock structure in 3-D unsteady potential flows

讲座摘要: We mainly talk about the dynamic stability of the steady 3-D wave structure of a planar normal shock front intersecting perpendicularly to a planar solid wall for unsteady potential flows. The stability problem can be formulated as a free boundary problem of a quasi-linear hyperbolic equation of second order in a dihedral-space domain between the shock front and the solid wall. The key difficulty is brought by the edge singularity of the space domain, the intersection curve between the shock front and the solid wall. This talk is based on a joint work with Professor Beixiang FangProfessor Feimin Huang, and Professor Wei Xiang.
