Mesh refinement analysis of the flow of a Maxwell fluid through an abrupt contraction
Abstract
We address the outstanding problem affecting the numerical simulation of viscoelastic flows, namely the existence of a critical value of the elastic parameter beyond which no discrete solution can be obtained. An extensive mesh refinement analysis conducted on a CRAY X-MP supercomputer indicates that limit points observed in the discrete solutions have a numerical origin.
