Evaluation script evalEff.sh

The evalEff.sh script can be found in tutorials. The current script version evaluates following quantities:

 

  • flow rates over pump inlet and outlet and all the interfaces
  • difference in inlet and outlet flow rates
  • pump power
  • pump efficiency for all components
  • pump torques on individual patches (viscous & pressure parts)
  • differences in total pressure for all components (area or flux averaged)
  • pump head corresponding to model components
  • static and total pressure at all the interfaces
  • forces acting on patches

Run the script evalEff.sh:

# bash evalEff.sh
A typical evaluation script output:
