Abstract

LAS VARILLAS EN UN ELEMENTO COMBUSTIBLE ESTAN DISPUESTAS EN LOS INTERSTICIOS DE UNA REJILLA. LAS INTERSECCIONES DE LA REJILLA SON DISTRIBUIDAS EN UNA DISPOSICION ESTRIADA PARCIALMENTE EN UN PLANO DE CRUCE AGUAS ARRIBA Y PARCIALMENTE AGUAS ABAJO. LAS LINEAS DE REJILLA (11,12,13,14) DISCURREN EN UNA DISPOSICION DE ZIGZAG ENTRE LOS DOS PLANOS. LA RESISTENCIA DE FLUJO ORIGINADA POR LAS LINEAS (11-14) Y/O POR LAS PALETAS (20,21,22,23) DE MEZCLADO DISPUESTAS PARA ELLO SE DESPLAZA EN PLANOS AXIALES DIFERENTES Y CONSIDERABLEMENTE REDUCIDOS.
