2D flow test rig


Thanks to its flexible design, a wide variety of seal geometries can be tested under numerous operating conditions. For example, labyrinth seals and adaptive seals.



  • Investigation of the flow behavior of seals - Determination of the leakage mass flow through seals of all kinds
  • A wide variety of seal tips and layer structures
  • Flexible axial and radial gaps possible
  • Automatic variation of the pressure boundary condition
  • Maximum pressure: 8 bar
  • Maximum flow rate 210g/s
  • Test bench width 300mm


Measurement technology & control

  • Pressure transducer
  • Automatic valve control
  • Temperatures (type T thermocouples)
  • Housing expansion
  • Mass flows (measuring orifice)
  • LabVIEW
