Title: A simple finite element method simulating the incompressible high Reynolds number flow and boundary layer separation. CCMA PDEs and Numerical Methods Seminar Series Yunhua Xue, Nankai University In this talk, we apply the simple finite element numerical scheme to simulate the vorticity-stream function formulation of the incompressible flow over a triangular domain and analyze its boundary layer separation. Compared with many classical finite element fluid solvers, this method avoids a Stokes solver, and only two Poisson-like equations need to be solved at each time step/state. Numerical experiments over this irregular domain for high Reynolds number $Re=10^4, 10^5$ flows are investigated. At same time, the dynamical mechanism of the boundary layer separation, including the bifurcation location and critical time are qualitatively reported.
