Abstract

REFERIDO A UN SISTEMA DE DISTRIBUCION DE FLUJO PARA UNA CORRIENTE DE FLUIDO DE MULTIPLES FASES. EL SISTEMA COMPRENDE: UNA ENTRADA PARA RECIBIR UNA CORRIENTE DE FLUIDO DE MULTIPLES FASES DESDE UNA TUBERIA DE ENTRADA; UNA PLURALIDAD DE SALIDAS CADA UNA PARA SUMINISTRAR UNA PORCION DE LA CORRIENTE DE FLUIDO DE MULTIPLES FASES A UNA RESPECTIVA TUBERIA DE SALIDA; Y, UN ALOJAMIENTO HUECO QUE FORMA UNA CAMARA INTERNA EN COMUNICACION FLUIDA CON LA ENTRADA Y LA PLURALIDAD DE SALIDAS, EL ALOJAMIENTO TIENE UN EJE LONGITUDINAL CENTRAL. LA CAMARA INTERNA TIENE UNA PRIMERA PORCION DE CAMARA ADYACENTE A LA ENTRADA Y UNA SEGUNDA PORCION DE CAMARA ADYACENTE A LA PLURALIDAD DE SALIDAS, Y LA PRIMERA PORCION DE CAMARA TIENE UN AREA DE SECCION TRANSVERSAL QUE ES MENOR QUE EL AREA DE SECCION TRANSVERSAL DE LA SEGUNDA PORCION DE CAMARA. UN DESVIADOR DE FLUJO NO PLANO ESTA SITUADO DENTRO DE LA CAMARA A FIN DE DEFINIR UN CANAL DE FLUJO DE AREA DE AREA DE SECCION TRANSVERSAL VARIABLE CONFORME SE MIDE EN UN PLANO ORTOGONAL AL EJE LONGITUDINAL CENTRAL DEL ALOJAMIENTO, PARA VARIAR LA TASA DE FLUJO DE LA CORRIENTE DE FLUIDO DE MULTIPLES FASES CONFORME ESTA PASA A TRAVES DEL CANAL DE FLUJO POR MEDIO DEL CUAL SE ESTIMULA LA MEZCLA TURBULENTA DE LA CORRIENTE DE FLUIDO DE MULTIPLES FASES EN LA CAMARA INTERNA. DICHO DISTRIBUIDOR DE FLUJO SE USA EN LAS INDUSTRIAS DEL SECTOR QUIMICO, MINERO, ENERGETICO E INDUSTRIAS RELACIONADAS EN PROCESAR UNA CORRIENTE DE FLUIDO DE MULTIPLES FASES O UNA SUSPENSION COLOIDAL
