  • An investigation towards determining the sources of uncertainty of a three-component three dimensional (3C3D) velocity measurement technique has been performed. The concept of the technique is velocity vector calculation based on 3D cross correlation of the intensity volume of positions of particles at a known time interval. Each volume is generated by scanning through depth of a micro-channel with a thin focal plane, capturing images, and stacking them together to build an intensity volume of particles’ position. The proposed 3C3D measurement system was used to measure the velocity vector field in mixing, segmented, and porous media micro-flows. It was observed that several system parameters have impact on measurement uncertainty. A Monte-Carlo simulation is developed to investigate the uncertainty affected by these parameters: generating synthetic images of the flow field, applying an extended 3D cross correlation algorithm, followed by a developed 3D elliptical Gaussian peak detection algorithm to calculate flow field.
