Abstract

UNA MEJORA RELATIVA A VENTILADORES AXIALES INCLINADOS HACIA ADELANTE (20) DONDE LA CAMARA DE EMPALETADA Y LA INCLINACION SE COORDINAN CON LA INCLINACION. LAS PALETAS (5) SE CARACTERIZAN POR UNA LINEA DEFINIDA POR LOS PUNTOS DE INCLINACION MAXIMA TIPO ARCO (FMAX) COMO UNA FUNCION DE CAMBIO DE LA POSICION RADIAL (R) DEL LADO DEL BORDE ANTERIOR (LE) DE LA LINEA DE MEDIO ARCO (MCL) A VALORES DE R, HACIA LA RAIZ DE LA PALETA (5) Y SE ENCUENTRA MENOS INCLINADO QUE EL BORDE ANTERIOR, LA LINEA DE MEDIO ARCO (MCL) Y EL BORDE POSTERIOR (TE). LA PALETA (5) SE INCLINA HACIA ADELANTE DE MODO QUE EL BORDE POSTERIOR (TE) DE LA PUNTA DE LA PALETA QUEDA AXIALMENTE DELANTE DEL BORDE POSTERIOR (TE) DE LA RAIZ DE LA PALETA. COMO RESULTADO, EL VENTILADOR (20) PRODUCE UNA CORRIENTE NORMALMENTE EQUILIBRADA RADIALMENTE, CON UN COMPONENTE REDUCIDO DE CORRIENTE PERPENDICULAR A LA CORRIENTE AXIAL DESEADA Y PERPENDICULAR A LA CORRIENTE TANGENCIAL. EL VENTILADOR COORDINADO (20) SE PUEDE COMBINAR CON UNA ESTRUCTURA DE CARCASA/BANDA (62,66) PARA CONTROLAR LA CORRIENTE DE AIRE QUE RECIRCULA EN UN CANAL (68) FORMADO ENTRE LA BANDA (66) Y LA CARCASA (62).
