Multidimensional method of spatially coupled approximation to the transverse escape in nodal codes; Metodo multidimensional de aproximacion espacialmente acoplada de la fuga transversal en codigos nodales

Abstract

A natural extension of the polynomic development programmed in RHENO code is presented, which adds to the variable order one-dimensional functions sum, a number of terms that represent functions of production. These new terms, which provide a direct determination of transverse escapes, are calculated from the new variables coupling among nodes: the 4 fluxes in rectangle vortices (bidimensional Cartesian geometry) or the 12 fluxes half-way through the parallelepiped edges (tridimensional Cartesian geometry). (Author). [Espanol] Se presenta una extension natural del desarrollo polinomico programado en el codigo RHENO, que agrega a la sumatoria de funciones unidimensionales de orden variable, terminos que representan productos de funciones. Estos nuevos terminos, que proveen una determinacion directa de las fugas transversales, son calculados a partir del acople de nuevas variables entre nodos: los 4 flujos en los vertices de los rectangulos (geometria cartesiana bidimensional) o los 12 flujos promediados sobre las aristas de los paralelepipedos (geometria cartesiana tridimensional).
