Simulators - Import export

with adjustable humidity and temperature to simulate the environmental conditions of a test specimen (e.g. household appliances, heating technology) The basis is a standard or climatic chamber (e.g. test kitchen, environmental simulation) with adjustable air humidity and temperature. On the basis of decades of experience in automotive test engineering, EP-E developed a concept in which the air flows in a circle (loop design). The result is a very excellent homogeneous temperature and humidity distribution. Through precise temperature and humidity control, it is possible to set different combinations of air conditioning and thus precisely adjust the required test conditions. The determination of the air flow (exhaust air volume) is carried out via a measuring section with the use of Laminar Flow Elements (LFEs). In order to determine the volume flow, pressure and temperature sensors are used to determine the air volume flow of the climatic chamber(s).

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.
