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.
- 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%
