Three-dimensional incompressible laminar and turbulent flows within a curved square duct are analyzed by using momentum equations in the physical component tensor form with a finite volume method for a boundary-fitted coordinate system. The solution algorithm is the SIMPLE method applied to the curvilinear coordinate. The closure of Reynolds equations is made by the standard two equation k-ε model. The use of equations by the physical component tensor form gives the superior accuracy for the analysis and the easier treatments for boundary conditions than by the semi-Cartesian form equations. The results are compared not only with the experimental data of an open literature but also with the results by a different method employing the semi-Cartesian form equations with a non-staggered grid system. In these comparisons, the solutions by the present method were in better agreement with the experimental data than those by the other method.
