✦ Synopsis

The fully developed two-phase turbulent isothermal Fanning friction factors for airviscoelastic fluid flows through a horizontal tube were measured experimentally. The viscoelastic fluids studied were aqueous solutions of polyacrylamide (100, 200, and 500 ppm by weight). Over the range of the apparent Reynolds number (Re a) from 10,000 to 100,000, the homogeneous model was found to be accurate enough for engineering prediction of turbulent friction factor for air-viscoelastic flows through horizontal tubes. A new correlation for the turbulent friction factor of air-viscoelastic plug flow is proposed.
