Computational Fluid Dynamics (CFD) can be used to accurately predict the behaviour of gases and fluids for rotating systems with both rotating and stationary components, for example mixers, motor rotors, bearings and bladed rotors such as compressors, turbines, pumps and fans.
For rotating machines, CFD offers significant advantages by providing:
- A quick route to comprehensive flow data, flow visualisation and performance predictions.
- Validation of designs before expensive testing and therefore reduced prototyping.
- Performance prediction over a range of operating conditions.
Highly three-dimensional swirling flows, turbulence and rotor-stator interactions are all readily simulated. Rotating system projects performed by TriVista cover a wide range of aerodynamic (or hydrodynamic for liquids) rotating system applications but typically have had objectives such as:
- Rotating system CFD analysis -Predicting the performance of turbo machines.
- CFD performance prediction – Evaluation of design changes on performance.
- Visualisation of flow features for greater understanding of flow behaviour.
- Windage loss calculations for rotors with complex geometries.
- Identifying poor flow regions (e.g. separation) causing loss and reducing the effects.
- Coupling of CFD model results with FE code to offer a full turbo-machinery multi-physics fluid and mechanical service also covering stress, thermal and dynamic issues.
- Rotating machinery CFD analysis & Turbo Machinery CFD analysis – Evaluation of novel turbo-machine concepts.
- Mixer performance analysis
- Turbine performance analysis
- Compressor performance analysis
- Windage loss analysis
