Today, the most successful companies use all available digital resources to develop the best products and processes for their customers. State-of-the-art virtual methods for design, product development and process development are key factors in achieving the highest performance and thus standing out from the competition.
In many technical applications, knowledge of the flow processes in the system under consideration is a key decision-making factor for the correct design of the product. CFD simulation (Computational Fluid Dynamics) can be used to visualise flow processes in components or assemblies. A numerical flow simulation can be used to analyse flows in three-dimensional space, which allows different flow parameters to be determined:
Pressure distributions and pressure losses
- Temperature distributions
- Heat transfer through flow
- Representation of the flow velocity
- Representation of the flow pattern (Does the flow proceed as expected?)
- Effect of pressures on mechanical components (fluid-structure interaction)
- Representation of multiphase mixtures (e.g. water-oil)
The following physical effects can be modelled for this purpose:
- Different flow conditions (laminar, turbulent)
- Compressible and incompressible flows (gases, liquids)
- Supersonic and subsonic flow
- FSI simulation (fluid-structure interaction)
- Heat effects and conjugated heat transfer (convection, radiation and conduction)
- Multiphase flow (mixing of different phases and material flows)
- Steady state and transient (time dependent)
- Complex geometries and moving meshes
