Momentum Transfer in Curved Pipes. 2. Non-Newtonian Fluids

Abstract

Experimental data for non-Newtonian fluids flowing through helical coils are presented. An appropriate viscosity term prevailing at the wall shear stress is defined and is used in the Reynolds number to obtain a correlation between friction factor and Dean number for helical coils. The use of differential viscosity in turbulent flow Reynolds number is found to give a single valued correlation for both the Newtonian and non-Newtonian fluids. © 1979, American Chemical Society.
