Abstract

English

The two dimensional Molecular Tagging Velocimetry (2D-MTV) is used to measure velocity fields of the flow in a micro mixer. Instead of commonly used micro particles an optical tagging of the flow is performed by using a caged dye. The pattern generation is done by imaging a mask for the first time. This allows to generate nearly any imaginable pattern. The flow induces a deformation of the optically written pattern that can be tracked by laser induced fluorescence. The series of raw images acquired in this way are analyzed quantitatively with a novel optical flow based technique. Reference measurements have been carried out allowing to draw conclusions about the accuracy of this procedure. A comparison to the standard technique of
