Solving the Conservation Equations in Fuel Rod Bundles Exposed to Parallel Flow by Means of Curvilinear-Orthogonal Coordinates

Abstract In this paper a method is described for constructing a curvilinear-orthogonal mesh grid. A method to perform calculations in such mesh grid is also illustrated. The method is demonstrated for the problem of laminar flow in rod bundle geometry. The comparison of the results with those of other authors is good.
