APPLICATION OF THE STANTON TUBE TO THE MEASUREMENT OF WALL SHEAR STRESS ON A FLAT PLATE WITH POLYMER EJECTION

An experimental investigation was made to determine the effects on drag of injecting aqueous solutions of polyethylene oxide into the turbulent boundary layer of a flat plate. The local mean wall shear stress was measured with a Stanton tube located in the laminar sublayer. Diffusion of the polymer in the boundary layer was also investigated by analysis of fluid samples withdrawn from the flat plate surface. In addition, a related but independent experimental turbulent pipe flow study was undertaken to determine any changes in Stanton tube sensitivity caused by the viscoelasticity of the polymer solutions.
