CFD-Analysis and what it can do.

CFD - Computational Fluid Dynamics - is based on the solution of partial differential equations describing a flow-area mathematically exactly.
These equations were independently discovered in the first half of the 19th century by two scientists, M. Navier and G. Stokes. The equations are called Navier-Stokes equations in honour of the two scientists concerned:
Navier-Stokes equations
Because of their complexity these equations can only be solved analytically in strongly simplified cases of fluid dynamics. But with the very rapid development of high-end computer technologies it has become possible to solve the general problem of a 3-dimensional viscous flow by means of advanced numerical calculation methods.
To use these methods the flow area has to be divided into a number of finite volume elements and boundary conditions (wall, inlet and outlet) have to be set at the border of the flow area. The accuracy of this method depends on the quality of the physical model, the fineness of the mesh and the accuracy of the iteration. Calculated results can be visualised with modern simulation software in almost any form desired by customers.
