Dieser Band enthält ausgewählte Beiträge des Workshops "Numerical Methods for the Navier-Stokes Equations", der vom 25-28. Oktober 1993 am IBM Wissenschaftlichen Zentrum in Heidelberg in Zusammenarbeit mit dem Sonderforschungsbereich "Reactive Flow, Diffusion and Transport" der Universität Heidelberg stattgefunden hat.
Themen sind fortgeschrittene Berechnungsmethoden für die Kompressible und inkompressible Navier-Stokes- Gleichungen in der Strömungsmechanik. Dies umfaßt Beiträge zu Variationsverfahren, Diskreditierungsverfahren und effizienten Gleichungslösern. Besondere Beachtung wird Problemen der Stabilität, Adaptivität und Parallelisierung geschenkt.

In addition to reducing the number of parameters, non-dimensionalized equation helps to gain a greater insight into the relative size of various terms present in the equation. Following appropriate selecting of scales for the non-dimensionalization process, this leads to identification of small terms in the equation. Scaling helps provide better understanding of the physical situation, with the variation in dimensions of the parameters involved in the equation. This allows for experiments to be conducted on smaller scale prototypes provided that any physical effects which are not included in the non-dimensionalized equation are unimportant. Pressure: there is no natural selection for the pressure scale. Where dynamic effects are dominant i. Where viscous effects are dominant i.

Fr is the Froude number and Re is the Reynolds number. For flows where viscous forces are dominant i. 0 then inertia terms can be neglected, leaving the equation of a creeping motion. Such flows tend to have influence of viscous interaction over large distances from an object. Where S is the salinity of the fluid, βT is the thermal expansion coefficient at constant pressure and βS is the coefficient of saline expansion at constant pressure and temperature. ST, TT denote the salinity and temperature at top layer, SB, TB denote the salinity and temperature at bottom layer, Ra is the Rayleigh Number, and Pr is the Prandtl Number.

All published items, including research articles, have unrestricted access and will remain permanently free to read and download 48 months after publication. Journal of Computational Physics has an open access mirror journal Journal of Computational Physics: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.

The Journal of Computational Physics focuses on the computational aspects of physical problems. The scope of the Journal is the presentation of new significantly improved techniques for the numerical solution of problems in all areas of physics. Letters to the Editor commenting on articles already published in this Journal will also be considered. Neither notes nor letters should have an abstract. Review articles providing a survey of particular fields are particularly encouraged. Published conference papers are welcome provided the submitted manuscript is a significant enhancement of the conference paper with substantial additions.

Reproducibility, that is the ability to reproduce results obtained by others, is a core principle of the scientific method. As the impact of and knowledge discovery enabled by computational science and engineering continues to increase, it is imperative that reproducibility becomes a natural part of these activities.

MATLAB is good for educational purposes, its recently been more used  in the high performance computing end. But it still has not gained the confidence of the scientific community for its high performance characteristics and that has been visible to me through filling the hundreds of job applications. COMSOL is emerging as a new contender for the CFD market but it will require several years to catch up.
