Understanding fluid-structure interaction in vibrating systems requires high-fidelity 3D flow measurements that conventional 2D PIV cannot provide.
Deploy and calibrate a 3D PTV system to characterize material-dependent FSI response across excitation frequencies.
Calibrated a LaVision DAQ system to ~50 µm positional uncertainty. Captured flow fields at >500 fps. Improved particle detection accuracy by 25%. Compared experimental results to ANSYS Fluent DPM simulations and MATLAB numerical analysis.
Validated numerical predictions within 7–10% error. Delivered quantitative FSI characterization data across multiple materials, directly supporting the DOE-funded CFAM research program.
