摘要：
This study investigates the forced convection flow of power law fluid through an annulus sector duct. The governing dimensionless form of momentum and energy equations is discretized by using a control volume-based method. Numerical solutions of the system of algebraic equations are obtained for different values of flow behaviour index, n, both for shear thinning fluids (0.3 <= n < 1) and shear thickening fluids (1 < n <= 2). Results for the quantities of interest both for the fluid flow and forced convection are discussed numerically and graphically for different values of n.
