Industrial valves operate under challenging service conditions involving high pressure, temperature, and frequent cycling. These complex environments often lead to structural deflection, sealing distortion, and unpredictable performance behavior.
Traditional analysis methods such as Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEA) provide useful results. However, they usually treat fluid and structural behavior separately. Fluid-Structure Interaction (FSI) modeling enables engineers to study the dynamic coupling between fluid flow and structural behavior in a more integrated and realistic manner.
