Abstract

An effective and practical method of producing strong constant-shear flow with a low turbulence level in the laboratory has been developed. A pair of closely spaced shaped gauzes with the upstream gauze of non-uniform porosity and the downstream gauze of uniform porosity was used for the generation of the flow. The method presented can be generalized to specify the gauze shape and porosity distribution necessary to generate other velocity distributions desired in a duct flow.
