Data reduction methods for flow tagging velocity measurements

Abstract

Data reduction algorithms for flow tagging velocity measurements are presented. Laser induced photochemical anemometry (LIPA) is the flow tagging technique used for the current experiments. This technique yields temporally and spatially resolved velocity and vorticity information. LIPA is first demonstrated in a laminar boundary layer. More complicated applications include a laminar boundary layer interacting with a flush-mounted, rotating disc, as well as a shear wake interaction with a circular cylinder. Advancements of the current study include the use of improved photoluminescent chemicals, as well as implementation of accurate image processing/data reduction algorithms. These yield typi..
