Objective
Non-intrusive PIV (Particle Image Velocimetry) technique has been used to measure the flow field inside a capillary pore. Fluorescence trace particles are being considered for blur-free imaging.
Approach
Particle tracers : Fluorescence seeding particle
Light sources : Argon-Ion laser
Light sheet optics : Combination of a cylinder lens and a spherical convex lens
Image detector : CCD camera
Vector analysis : La Vision software for PIV
