Experimental study of lid-driven cavity flows in the Lagrangian frame of reference

This research of lid-driven cavity (LDC) flows is motivated by their importance to many fields of polymer production, coating and polishing in microelectronics. Moreover, LDC flows represent almost all phenomena that can possibly occur in incompressible flows in finite domains with strong mean shear. In this research we present experimental study that aims at the important physical aspects of LDC flows by emphasizing on three-dimensional and Lagrangian features. We utilized the non-intrusive optical experimental methods of two-dimensional particle image velocimetry and three-dimensional particle tracking velocimetry (3D-PTV), which should shed new light on the LDC flows in rectangular and cubic domains. The experiments performed in laminar, transitional and turbulent regimes of the LDC flow.
