Optical Measurements of Fluid-Structure Interactions

LaVision’s FlowMaster FSI system is designed to offer a flexible and innovative way to experimentally investigate the dynamics of a deformable and/or moving structure and the external or internal fluid flow that interacts with it.
These Fluid-Structure Interactions are described through the use of synchronized Particle Image Velocimetry (PIV) and Digital Image Correlation (DIC) measurements. Using these non-intrusive and full-field techniques, the FlowMaster FSI system enables simultaneous fluid flow diagnostics and structural deformation and strain, that allow the user to perform a direct and intuitive analysis of such complex phenomena.

Bioscience Applications

The investigation of Fluid-Structure Interactions in Bio-engineering applications is acutely challenging, because separate techniques are usually required to measure the fluid flow and surface deformation. Using FlowMaster FSI systems, innovative research and new insights into this area of expertise is uncovered.
