Pump Multi-Disciplinary Optimization

In this application, the goal is to perform the optimization of a radial pump. The goal is to modify 13 parameters of the geometry to increase the pump efficiency while keeping the mechanical stresses below a maximum value and using constraints on the mechanical vibration mode of the pump.

  • We achieved high robustness of this complex simulation chain
  • The optimization using 13 parameters in a few design cycles (less than 50 simulations of the whole pump performance)
  • The difficulties of optimizing with the vibration modes introduced a strong local minimum in the design space that could only be solved thanks to our extremely powerful optimization technique.
  • The efficiency is increased from 86.4 % to 88.5 % while respecting 30 mechanical constraints
