Turbomachinery CFD simulations

Turbomachinery CFD simulations are one of my core competencies. As an aerospace engineer with several years experience in fan, blower, compressor and turbine simulations I can help you with rotating machinery analysis and development. A rotating machine can be investigated by its aerodynamic, thermal and aeroacoustic properties. All these qualities can be simulated via Computational Fluid Dynamics technology.


Typical outcomes from a turbomachinery CFD analysis

There are standard analysis results that can be obtained from a numerical simulation for turbomachines. Most users are interested in the pressure change versus flow rate relationship – the very core information a CFD simulation provides. Here is a list of the additional outcomes:

  • performance improvement options
  • pressure rise
  • pressure loss
  • velocity profiles
  • efficiency
  • pressure ratio
  • backflows
  • blade flow profiles
  • temperature distributions
  • outlet flow profiles

Turbomachinery CFD application areas

Numerical simulations can be applied to any machine that has rotating part(s). The rotating or alternating movement can be simulated by using several different techniques, depending on the required accuracy level.

Some of the rotating machinery types:

  • centrifugal compressors
  • axial compressors
  • cooling fans
  • ventilation systems
  • radial blowers
  • cross-flow blowers
  • water pumps
  • water turbines

The necessity to develop more efficient turbo devices requires deeper understanding the factors contributing  to performance and fine tuning them. Providing solutions for turbomachinery design and performance optimization through computer aided simulations has never been easier and more cost-effective than today.

With detailed information on the flow pattern inside compressors, turbines, pumps and blowers, CAE engineers can quickly optimize the design (blade geometry, flow angles, mass flow rate and pressure drop) to improve the performance right from the early stage of the design.

Simulation driven design for turbomachinery helps to identify key factors affecting the device performance and provide alternatives and efficient design concepts. With virtual computational fluid dynamics simulations the number of prototype tests are reduced significantly while the number of virtual prototypes remain unlimited. Through reduction in measurements, CFD helps turbomachinery engineers to reduce the turn-around time for development and improve the product much faster.
