Abstract:

A prototype Vorticity Optical Probe VOP electro-optical system, data reduction and analysis procedures, and algorithms were developed and tested in this Phase II SBIR program. Also, a new type of VOP probe particle, made with acrylamide gel, was invented in this program. This achievement permits the VOP to be used in water. The VOP system was employed in a study of the vorticity fields in several precision Couette flow regimes. The measured vorticity statistics compared favorably with expected values. Several new results are reported.
