    Parallel computation has shown to provide considerable potential for the numerical simulation of complex three-dimensional flows. A number of studies have shown that CFD codes can be parallelized for efficient use on present-day parallel computer systems. However, of particular importance for industrial applications is the total time to solution, comprised not only of the resolution of the flow equations but also the pre- and post-processing phases. Results are presented of a study of the use of high-performance parallel computing to facilitate such numerical simulations. This study is being undertaken using a 256-processor Cray T3D system, within the framework of the joint Cray Research--EPFL Parallel Application Technology Program. 1 FLOW SOLVER The parallel code used in this study is based on a multi-block code developed within IMHEF-EPFL for the numerical simulation of unsteady, turbulent, incompressible flows. This code solves the Reynolds-averaged Navier-Stokes equations on 3D ..

    this paper, we will concentrate on single phase flows avoiding any attempt to handle chemical reactions, giving some examples that indicate the state-of-the-art capabilities of CFD applied to particular relevant chemical engineering applications. The paper is organized as follows. In Section 2, the modelling of glass flow in large melting furnaces is surveyed. New links to control theory are mentioned, sheddding some light on interdisciplinary design approaches. Section 3 reports on new developments about three-dimensional transient simulation of viscoelastic fluids. Finally, Section 4 presents the results obtained by parallel computation of an incompressible fluid in an in-line static mixer. 2 Glass flow modellin
