摘要：

This study examines the resolution of the Navier-Stokes equations for laminar natural or forced incompressible flows by means of the domain decomposition method. Conservative and nonconservative interpolation schemes available in the literature are studied and compared to a formulation based completely on finite-volume techniques. The discretized governing equations are obtained in each subdomain using a finite-volume method on staggered grids and are solved adopting a pressure-based segregated algorithm. A mesh refinement study and the generalized Richardson extrapolation have been adopted to evaluate the errors and the order of accuracy of each interpolation scheme. Illustrative numerical results of a complex flow through a junction are shown.
