Abstract

EL OBJETIVO DE LA INVENCION ES DISEÑAR UN RECEPTOR DE FLUJO DE PASO VORTICAL DONDE EL CAMPO A TRAVES DEL NUMERO STROUHAL ES CONSTANTE, EXTENDIENDOSE HACIA UN NUMERO DE REYNOLDS BAJO Y QUE SUMINISTRA UNA DISPERSION DE MEDICION BAJA Y CON LA CAPACIDAD PARA DETERMINAR EL NUMERO STROUHAL DE FORMA PRECISA DENTRO DEL CAMPO EN DONDE LA RELACION DE LA CUOTA DE FLUJO DE VOLUMEN CON RESPECTO A LA FRECUENCIA DE RESTRICCION VORTICAL ES CONSTANTE. ESTE OBJETIVO SE CONSIGUE EN VIRTUD DEL HECHO DE QUE UN ELEMENTO (1) DEFLECTOR ESTA MONTADO DE FORMA SEGURA A PUNTOS OPUESTOS DIAMETRALMENTE SOBRE LA CARA INTERIOR DE UN TUBO (2) DE MEDICION, DE DIAMETRO INTERNO D, A TRAVES DEL CUAL FLUYE UN FLUJO, O SE FIJA EN UNA ESTRUCTURA COLOCADA EN EL TUBO. EL ELEMENTO DEFLECTOR CONSISTE, SOBRE EL LADO DEL FLUJO INCIDENTE, EN UN ELEMENTO (11) PLANO CUYA SECCION TRANSVERSAL ES UN TRAPECIO DE ALTURA L{SUB.1} Y BASE B{SUB,1} Y B{SUB,2} Y QUE ESTA UNIDO, DEJANDO UN ESPACIO, A UN ELEMENTO (12) DE ESTELA CUYA SECCION TRANSVERSAL ES UN TRIANGULO DE ALTURA L{SUB,2} Y BASE B{SUB,3}. SE APLICAN LAS SIGUIENTES ECUACIONES DE MEDICION: 0,1 MENOR IGUAL DE B{SUB,1}/D MENOR, IGUAL 0,35; 0,6 MENOR IGUAL B{SUB,2}/B{SUB,1} MENOR IGUAL 0,95; 0,1 MENOR IGUAL L{SUB,1}/B{SUB,1} MENOR IGUAL 0,2; 0,75 MENOR IGUAL L{SUB,2}/B{SUB,1} MENOR IGUAL 1,5; 0,5.B{SUB,2}/B{SUB,1} MENOR IGUAL B{SUB,3}/B{SUB,1} MENOR IGUAL B{SUB,2}/B{SUB,1}.
