Abstract

LA GEOMETRIA DE UN CANAL DE FLUJO (1) SE PUEDE VARIAR DENTRO DE UNA GAMA AMPLIA SI POR LO MENOS UNA DE LAS PAREDES DEL CANAL DE FLUJO (1) SE REALIZA EN FORMA DE PAQUETE DE CHAPAS (2) QUE SE PUEDA INTRODUCIR MAS O MENOS EN EL CANAL MEDIANTE UNOS DISPOSITIVOS DE AJUSTE (7), DESDE LA CARA POSTERIOR. LA REGULACION PUEDE SER O BIEN UNIFORME EN TODA LA ANCHURA DEL CANAL DE FLUJO (1), O SOLO LOCALIZADA EN DETERMINADOS PUNTOS DEL CANAL DE FLUJO (1). DE ESTA MANERA SE ESTA EN CONDICIONES DE MODIFICAR DESDE EL EXTERIOR, MIENTRAS UN MEDIO FLUYE A TRAVES DEL CANAL DE FLUJO (1), O BIEN LA RESISTENCIA AL FLUJO DE LA TOTALIDAD DEL CANAL O LA RESISTENCIA AL FLUJO EN DETERMINADOS PUNTOS, MODIFICANDO DE ESTA MANERA EL CONJUNTO DEL FLUJO DE MASA O LA DISTRIBUCION DEL FLUJO DE MASA EN LA FORMA DESEADA. GRACIAS A LA SUPERIOR FLEXIBILIDAD QUE PRESENTA EL PAQUETE DE CHAPAS (2) CON RESPECTO A LAS PAREDES DE CANAL MACIZAS SE OBTIENEN NUEVAS POSIBILIDADES TECNICAS DE PROCESO.
