3C velocity field measurement in microscale using time resolved micro-PIV

摘要

Measurement of the 3C velocity field in the microfluidic devices with the conventional techniques and conventional micro-PIV is still difficult due to the limited optical access to the microscale flow fields. Mainly micro PIV vector field realizations have been remained limited to 2C velocities. In this study, 3C velocity measurement in microscale using 2-dimentional time-resolved micro PIV images is proposed. The method is based on the PIV performs cross-correlation (CC) peak height tracking inside the small ensembles of the TR-PIV images. This concept was also demonstrated basically by an experiment in an inclined micro tube.
