Behavior of multiphase cryogenic fluids

experimental und numerical investigations

With the help of this basic research project, processes that occur during the sudden evaporation of cryogenic media should be better understood, described and evaluated. This should create possibilities for improved design and efficient operation of safety elements and power transmitting components in plants with cryogenic media.
A well-founded theoretical understanding of the dynamic calculation and evaluation of boiling cryogenic media will be developed. In order to obtain, for example, a concrete component behaviour under cryogenic conditions, numerical descriptions are required beyond the design calculations, both for fluid dynamics and for the spatial and temporal change in temperature.
Parallel to this, the experimental basis for the design of complex cryogenic components and systems engineering is being improved.
The objectives and results of the preliminary research project include

  • Calculated parameters from various numerical simulations for essential cryogenic components
  • Extensive experimental results for variations of the underlying geometry, advantageous process control, improved design of components
  • Basic thermodynamic processes in gas chillers
  • Calculation algorithms for the description of dynamic heat transport phenomena
  • Evaluation of critical plant conditions
  • Suitable materials for cryostat components and cryogenic plants
  • Novel components e.g. for small helium mass flows

An application project for the development of heat exchangers for cryogenic multiphase fluids is planned.
