Investigations on the opartional behaviour of liquid injected screw-type expanders

Title: Investigations on the operational behaviour of liquid injected screw-type expanders
  • Analysis of physical effects on the operating behaviour of liquid injected screw expanders
  • Development of simulation tools considering multi-phase flow in screw-type expanders


  • operation evaluation by means of characteristic maps
  • pressure indication in working chamber and clearances
  • detailed investigations on different physical mechanisms
  • flow visualisation in working chamber – examination of liquid distribution




  • modelling and implementation of physical effects resulting from liquid injection (heat transfer, phase transition, hydraulic losses)
  • detailed CFD simulations (inlet port, clearance flow)
  • theoretical investigation of screw-type expanders by means of multi-chamber simulations
