题 目: A spectral vanishing viscosity method for stabilizing viscoelastic flows
报告人: 马 侠 博 士 (Brown University, USA)
abstract: A new method for stabilizing viscoelastic flows is proposed suitable
for high-order discretizations. It employs a mode-dependent diffusion operator
that guarantees monotonicity while maintaning the formal accuracy of the
discretization. Other features of the method are: a high-order time-splitting
scheme, modal spectral element expansions on a single grid, and the use of a
finitely extensible non-linear elastic-Peterlin(FENE-P) model. The convergence
of the method is established through analytic examples and benmark problems in
two and three dimensions, and unsteady flow past a three-dimensional 3D
ellipsoid is studied at high Reynods number.
