Title: Numerical Methods for Incompressible Newtonian Fluid Flow Speaker: Professor Zhiqiang Cai, Purdue University Time and place: Thursday May 1st 3:30pm at REC 307 Abstract. For incompressible Newtonian fluid flow with homogeneous density, the primitive physical equations are the conservation of momentum and the constitutive law. This is a first-order partial differential system for the physical stress, velocity, and pressure. By differentiating and eliminating the stress, one obtains the well-known second-order incompressible Navier-Stokes equations in the velocity-pressure formulation. Although substantial progress in numerical methods and in computations has been achieved, the Navier-Stokes equations may still be difficult and expensive to solve. In this talk, we will first derive the stress-velocity formulation for incompressible Newtonian fluid flow and then study numerical methods based on this formuation.
