Uncertainty analysis of PIV measurements in bubbly flows considering sampling and bubble effects with ray optics modeling

Validation and uncertainty quantification of multiphase-CFD solvers: A data-driven Bayesian framework supported by high-resolution experiments

“…With the PIV-PLIF system, the bubble-induced light distortion in the PIV measurement can be mitigated. Additional uncertainty analysis through ray optics modeling also confirms the distortion from bubble on PIV measurement can be filtered out through multi-pass post-processing technique [43], thus PIV-PLIF can be regarded as a valid tool for liquid phase measurement in two-phase flow systems. Highspeed camera is a mature tool to visualize two-phase flow interfacial structure.…”
