Parallel computation of incompressible flows with complex geometries. (English) Zbl 0882.76044

We present numerical methods for the solution of large-scale incompressible flows with complex geometries. These methods include a stabilized finite element formulation of the Navier-Stokes equations, implementation of this formulation on parallel architectures such as the Thinking Machines CM-5 and the CRAY T3D, and automatic three-dimensional mesh generation techniques based on Delaunay-Voronoï methods for the discretization of complex domains. We apply these methods to the simulation of airflow past an automobile and fluid-particle interactions.
