Flow inside pipes and through valves is a complex phenomenon. In pipe system design, especially in valve design, engineers are increasingly adopting CFD technology for analysis and design optimization.
Polaris CFD software has recently been applied in hydraulics and pneumatics industry successfully. Handling complex geometry, combined with moving geometry enables Polaris CFD to simulate the entire opening and closure of valves.
