Abstract

A steady fully-developed laminar flow of power-law fluids in curved pipes has been solved numerically for Dean numbers D<1000, power indices 0.5<n<1.0 and curvature radius ratios 10<Rc<100. Velocity profiles of primary flow, stream lines of secondary flow, distributions of wall shear stress and friction factors are obtained. Effects of D, n and Rc upon flow characteristics made clear.
