PARALLEL COMPUTATION OF ROTATING FLOWS

Parallel Computation of Viscous Flows

In this study we describe parallel iterative and direct solution strategies for viscous flow computation using domain decomposition. Both stream function vorticity and primitive variable formulations are considered. The basic ideas associated with the element-by-element approach and subdomain approach can also be extended to other cell or control-volume approximate formulations. Numerical resul...

Finite Element Distributed Computation for Viscoelastic Rotating Flows

This paper is concerned with the parallel computation of incompressible viscoelastic rotating flows. Such flows arise in many industrial settings being particularly important in the food industries, for materials such as dough. Here, the material is driven by one or two stirrers, rotating about the centre of a cylindrical vessel, fixed to a lid. The stirrers may be positioned in eccentric arran...

PARALLEL FINITE ELEMENT COMPUTATION OF 3D INCOMPRESSIBLE FLOWS ON MPPs

In this chapter we present numerical simulations of the Navier-Stokes equations with the stabilized finite element methods on the massively parallel CM-5 supercomputer. These computations are based on implicit methods and their implementations are based on the assumption that the mesh is unstructured. The use of matrix-free iterations eliminates the need to store element-level matrices, thus pr...

Parallel computation of unsteady compressible flows with the EDICT

Recently, the Enhanced-Discretization InterfaceCapturing Technique (EDICT) was introduced for simulation of unsteady ̄ow problems with interfaces such as twōuid and free-surface ̄ows. The EDICT yields increased accuracy in representing the interface. Here we extend the EDICT to simulation of unsteady viscous compressible ̄ows with boundary/shear layers and shock/ expansion waves. The purpose is...
