MENDOZA-RESENDIZ, Alejandro  and  BEREZOWSKY-VERDUZCO, Moisés. Numerical solution of potential flow in complex geometries. Tecnol. cienc. agua [online]. 2011, vol.2, n.2, pp.183-192. ISSN 2007-2422.

A methodology for the numerical computation of potential flow using composite curvilinear grids is presented. Curvilinear grids can be adapted to physical domains with irregular geometry. However, in complex geometries this is not enough; in such cases, composite grids should be used, which are formed by multiple interconnected blocks. This paper shows that the use of domain decomposition techniques provides an efficient methodology for solving this kind of problems, obtaining the solution first at the interface, and later in each block. In order to validate the proposed methodology a comparison with analytical solutions is performed. An application case is also presented.

Keywords : potential flow; composite grids; curvilinear grids; domain decomposition.
