Fluid mechanics lab

The fluid mechanics group combines flow measurement (µPIV, PIV, LDV of single- and multiphase systems) with numerical flow simulation (with commercial and open source tools). Interdepartmentally, the fluid mechanics group works on the investigation of flow phenomena, the improvement of flow geometries and development of innovative measurement techniques.

Laser lab

At ZBT different flow measurements are performed in the laser lab. To investigate and analyse flows modern laser-optical measurement systems are used: Laser-Doppler-Velocimetry (LDV) and Particle-Image-Veloci­metry (PIV) are non-intrusive, particle based measurement techniques that are very well suited to analyse flow phenomena on small and large scales based on the measurement of flow velocities.

  • Laser-Doppler-Velocimeter (fp50unshift-532nm, 75mW; ILA GmbH)
  • Particle-Image-Velocimetry system (125mJ Nd:YAG double pulse laser, CCD cameras, High-Speed camera, Scheimpflug-adapters; LaVision GmbH)
  • Micro-Particle-Image-Velocimetry system (2x10mJ Double Cavity High-Speed laser, inverted epifluorescent mikroscope, CCD-camera; LaVision GmbH)

Numerical flow simulation


At ZBT different tasks concerning fluid mechanics, thermo-fluidics and multi-physics are investigated and analysed by CFD methods. The following equipment is used:

  • different workstations (up to 64 GB RAM and 12 cores)
  • software: AVL FIRE (incl. Fuel Cell Module), ESI CFD-ACE+ (incl. Fuel Cell Module), OpenFOAM
