ABSTRACT

In this study, we present a numerical solution for three dimensional laminar flow of Herschel-Bulkley

non-Newtonian fluids in the entrance region of a rectangular duct. The governing equations are solved

iteratively by using finite difference method to obtain velocity components, pressure and friction

factor. Modifications in computations of the transverse velocities by introducing a second order

accurate finite difference representation of the differential form of the continuity equation are

presented in this study. The results are presented in Tables and Figures for different parameters for the

fluid and the duct geometry.
