Abstract

Se describe un método y un aparato para hacer fluir un fluido sobre una superficie plana inclinada a través de la anchura total de la ranura que tiene un numero de capilaridad menor de 0.04. La separacion S de la salida de la ranura se selecciona para que sea menor que (I) donde S es la separacion de la ranura en cm,æ es la viscosidad del fluido medida en poise, p es la densidad del fluido medida en gm/cm3, o es la tension superficial del líquido medida en dinas/cm, y Nre es el numero de Reynolds definido como Nre = 4M/æ, donde M es la velocidad de flujo del fluido por unidad de anchura, medida en gm/seg-cm. La expresion para a está definida como 0.981 + 0.3406 log Nre 0.3406. El fluido se hace fluir a través de una salida de ranura.
