Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Global existence and decay of solutions to compressible Prandtl system with small analytic data
少量分析数据 可压缩 Prandtl系统解 全局存在 衰减
2023/4/18
In this talk, we shall prove the global existence and the large time decay estimate of solutions to compressible Prandtl system with small initial data, which is analytical in the tangential variable....
Nonlinear superposition of direct and inverse cascades in two-dimensional turbulence forced at large and small scales
Nonlinear superposition direct inverse cascades two-dimensional turbulence

Abstract: We inquire the properties of 2d Navier-Stokes turbulence simultaneously forced at small and large scales. The background motivation comes by observational results on atmospheric turbulence. ...
A new method of quality improvement for quadrilateral mesh based on small polygon reconnection
Mesh improvement Topological clean-up Quadrilateral mesh Small polygon reconnection
2012/2/24
In this paper, a new method of topological cleanup for quadrilateral mesh is presented. The method first selects a patch of mesh around an irregular node. It then seeks the best connection of the sele...
Effect of swirling flow on platelet concentration distribution in small-caliber artificial grafts and end-to-end anastomoses
Platelet near-wall concentration Swirling flow Small-caliber arterial grafts End-to-end anastomosis
2012/2/29
Platelet concentration near the blood vessel wall is one of the major factors in the adhesion of platelets to the wall. In our previous studies, it was found that swirling flows could suppress platele...
Tensors of finite rotations and small strains on the middle surface of a shell
non-linear shell theory finite rotations small strains middle surface
2010/3/12
On the middle surface of the shell, the displacements as well as the rotations of the base vectors are finite, the strains are, however, considered to be infinitesimally small. The rotation of the bas...
