Abstract
Abstract An integral solution for Herschel-Bulkley fluid flow development in a straight channel is presented. The analysis not only accounts for the loss of energy due to viscous dissipation in the boundary layer, but evaluates wall-shear stress as integrals involving axial velocity distribution, which is obtained by cross-sectional integration of the equation of momentum. Results are compared with other integral solutions for several values of Herschel-Bulkley number and flow behavior index.
