Topic of lecture:Dual-porosity-Stokes model and finite element method for coupling dual-porosity flow and free flow

Lecturer: He Xiaoming (associate professor of Missouri University of Science and Technology, United States)

Time of lecture: Friday, Jan. 5, 2018,4:30 - 5:30 p.m.

Location of lecture: Mingli Building A514

Abstract:In this presentation we will first introduce the immersed finite elements to efficiently solve elliptic interface PDEs on structured meshes. Then two applications to the problems of charging in space will be discussed: the ion thruster and the electrostatic levitation of lunar dust. The latter one is one of the greatest inhibitors to a nominal operation on the moon. Finally, the immersed finite elements will be extended to a moving interface PDE for more applications.
