| Summary: | 碩士 === 中原大學 === 機械工程研究所 === 92 === This thesis investigated the fully developed laminar flow in ducts with arbitrary cross section shape using a numerical approach. The numerical results were then compared with available analytical solutions. The fully developed flow field in ducts with hydraulic diameter 100μm was computed to study the relationship among the friction factor, the mean laminar flow velocity and the maximum flow velocity value and the geometrical parameters. The governing equations were discretized with triangular cells using a finite volume method with an unstructured grid arrangement. The steady incompressible laminar flow was computed for Newtonian and Non-Newtonian fluids in arbitrary ducts under the assumption of fully developed flow. The numerical results were found to be in good agreement with the analytical solutions.
