Best Practices For Volume Flow Rate Measurements Using Piv At The Exit Of A Turbulent Round Jet, Robert Schaap Aug 2017

Best Practices For Volume Flow Rate Measurements Using Piv At The Exit Of A Turbulent Round Jet, Robert Schaap

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Particle image velocimetry (PIV) is an optical flow measurement technique that is used to measure volume flow rate at the exit of a turbulent, round nozzle. The objective of this thesis is to determine how to best make this measurement. The quality of the measurement is affected by a range of data acquisition parameters and how data are processed. Measurements are made over a range of different flows using the two main types of PIV: Two Component (2C), which uses one camera, and Stereo, which uses two cameras, similar to human eyes. Previous work done for data acquisition and processing …


Uncertainty Of Stereo Piv Calibration And Self-Calibration, Braydon J. Williams May 2017

Uncertainty Of Stereo Piv Calibration And Self-Calibration, Braydon J. Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Particle image velocimetry (PIV) is a widely used fluid measurement technique. Three dimensional PIV data or stereo PIV is acquired using two cameras. Stereo cameras are calibrated from camera coordinates, pixels, to real world units such as millimeters using calibration models. Stereo calibration is fundamental to the accuracy of a PIV measurement. In this thesis, the accuracy of the stereo calibration is assessed. The mean error of stereo calibration was found to be 0.23%.
