Abstract
Using the high-order finite element method, we provide
accurate predictions of the friction factor and the
Nusselt number for the fully developed laminar flows of
power-law-type non-Newtonian fluids in rhombic,
isosceles-triangular, elliptical, and semielliptical
ducts. Two kinds of thermal boundary conditions, commonly
referred to as the H1 and T conditions, are considered.
For each type of duct, computed results are presented for
several aspect ratios with the power-law index ranging
from 0.2 to 1.0. Mesh refinement tests with four
different meshes are carried out for two specific duct
configurations, indicating that the present predictions
are remarkably insensitive to mesh density.
