Control Valve Optimization

CFD-Driven Shape Optimization of a Control Valve

Control valves are used in a wide range of industries, and they regulate the flow of various fluids. For a project at ARCA Valves, the flow through such a control valve needed to be optimized.

The challenge was to design a flexible parameterized geometry model of the valve housing that additionally incorporated a set of constraints (wall thicknesses, flange definitions).

For the CFD part, Autodesk Simulation CFD was used. The parametric geometry model was created within CAESES.

Key Benefits

  • A robust and flexible model was created
  • After a DoE and a quick multi-start points local optimization, the improvement in terms of pressure drop was 5.6%
  • By drawing conclusions from the DoE study, the parameter limits were again adjusted and the objective was finally improved by ~27%
