Abstract: The detailed formulae of Navier-Stokes equations in the orthogonal curved coordinate system, the numerical methods for the integration of the momentum equations and the solution of Polisson equation of pressure are described. The fully developed laminar flow in acurved duct of rectangular cross-section is simulated numerically and the results are compared with other results.

Key words: laminar flow, curved duct of rectangular, numerical simulation
