Mathematics Colloquium: Jie Shen (Purdue)

  • Date: 11/25/2010
Lecturer(s):

Jie Shen, Department of Mathematics, Purdue University

 

Location: 

University of British Columbia

Topic: 

Phase-field models for multiphase complex fluids: modeling, numerical analysis and simulations

 

Description: 

I shall present an energetic variational phase field model for multiphase incompressible flows which leads to a set of coupled nonlinear system consisting a phase equation and the Navier-Stokes equations. We shall pay particular attention to situations with large density ratios as they lead to formidable challenges in both analysis and simulation.

 

I shall present efficient and accurate numerical schemes for solving this coupled nonlinear system, in many case prove that they are energy stable, and show ample numerical results which not only demonstrate the effectiveness of the numerical schemes, but also validate the flexibility and robustness of the phase-field model.
