Whether power plants run on nuclear or fossil fuels or on renewable energy sources, the complex plant systems and individual components must be capable of performing their designated functions under normal and accidental operating conditions.

We propose flow model tests to support the design process, design validation and optimization using experimental test rigs based on similarity laws for the following tests:

  • Reduced-scale models for systems and components testing, during the design phase for example
  • Experimental validation of results from flow simulation models generated with computational fluid dynamics.

Our experimental setups guarantee the physical similarity of the modeled flow phenomena to the real flow conditions in the actual plant equipment. To this end, fluids used for experiments are chosen with simplicity and practical economics in mind, such as water and air. Applying appropriate similarity laws makes it possible to apply the experimental results to actual in-plant flow conditions, even when the actual fluids in the plant are flue gas, steam or oil.
