ABSTRACT
Abstract:
Particle Image Velocimetry (PIV) is a whole-flow-field measurement technique, providing instantaneous velocity measurements in a cross-section of a flow field. Two velocity components are typically measured, but use of a stereoscopic approach allows for the instantaneous recording of all three-velocity components, resulting in instantaneous 3D velocity vectors for the whole area of interest. The seminar will present theory, implementation, and some recent applications of PIV. The detailed coverage of basic principles will include description of PIV measurement process and parameters influencing the measurement for macro and micro scales, correlation analysis, seeding and illumination considerations, measurable velocities, spatial and temporal resolution, dynamic range, measurement optimization, error factors; stereoscopic viewing and Scheimpflug condition for planar 3-D measurements.
