Simulators - Import export

A further area of activity of Suvis is the development and application of modern numerical methods for the calculation (prediction) of flows using CFD in industry, science etc. Our employees are especially trained in view of technical applications of numerical flow simulations. Within the recent years we conducted several projects in the area of multiphase flows. We dealt with applications in the optimisation of processes in chemical engineering, the transport of particles, gas cleaning and particle separation from gases and liquids, and the calculation and optimisation of cyclone separators. We apply powerful commercial software tools like grid generators in order to generate numerical grids using CADdata in a short time for even complex applications. Also, for flow calculations and the evaluation of 3D flow fields we apply powerful software solutions. Furthermore, for certain individual problems we apply codes we have developed our selves.

The Suvis GmbH also deals with the application of modern numerical methods for the lay out and optimisation of various separator types like cyclones. A typical application of these computation methods is the computer aided investigation of particle separation from gases in cyclones. The prediction of the separation efficiency allows the reliable optimisation of conventional cyclones and the development of completely novel high efficiency cyclones. With that, very often expensive filter units, wet cleaner, or costly electro filters can be replaced or completed. When applying numerical methods (CFD simulations) to cyclones one encounters the problem of strong curvature of the stream lines because of the resulting strong swirl flow and the abrupt change of flow direction towards the outlet tube. This means that the assumption of isotropic turbulence is not useful anymore.
