CFD (Computational Fluid Dynamics)

Flowtech Industries AG is licensed to use the state of the art commercial CFD software Fluent. Our competence in its application is based on 10 years of experience in numerical flow simulation. Computational Fluid Dynamics represent a sophisticated analysis technique which is able to predict the flow behaviour in countless applications by solving thousands of differential Navier Stokes equations nummerically in a relatively short period of time. Moreover, the software is not limited to predict the flow behaviour of a random fluid but it is able to reproduce heat and mass transfer (e.g. conduction, convection, radiation, perspiration and dissolution), phase changes (e.g. freezing and boiling), chemical reactions (e.g. combusion) and mechanical motion (e.g. impeller rotation). The application of CFD software requires qualified and experienced engineers. Thus, realistic and accurate results are obtained. In addition to this, the definition of appropriate boundary conditions and the generation of an adequate grid have a strong impact on the quality of the results.

CFD analysis is the synthesis of decades of research in various fields such as applied mathematics, computer sciences, physics and engineering sciences. Computational Fluid Dynamics are currently being applied in the aerospace, automotive, mechanical, manufacturing, medical and chemical industries, among others. Specific applications include the analysis of gas turbines, airfoils, engines, exhaust systems, pumps, fans, heat exchangers, mixers, chemical reactors, boilers, catalytic reducers, weather related phenomena, arterial blood flow and many more.

Our computing center is able to run several complex calculations in parallel.

The ability to combine numerical and experimental flow modelling makes Flowtech Industries AG a strong and competent partner.

Examples of Flowtech CFD applications are listed below.
- flow and velocity distribution optimization inside ductworks
- pressure drop minimization
- ductwork design
- temperature visualization
- static mixer optimization
- fluid mixing in general
- chemical reactions
- multiphase flow (e.g. FGD)
- turbine and pump optimization

The analysis of high dust SCR plants requires an experimental approach (experimental flow modelling). CFD can be applied complementary. Fly ash and particle transport require to be reproduced experimentally. The numerical approach is less accurate due to the difficulty to reproduce important phenomena related with the particle transport.
