Abstract

Procedimiento para reducir el ruido en la estrangulación de flujos de vapor y de gas, donde corrientes divididas fluyen a velocidades diferentes, caracterizado porque los flujos en un primer trayecto en corto recorrido se expanden supercríticamente, después, en un segundo trayecto directamente a continuación, se dividen varias veces y se deceleran, siendo las secciones de flujo de los canales en el segundo de los trayectos individualmente más pequeños que en el primero de los trayectos pero en su totalidad considerablemente mas grandes que la totalidad de las secciones del primero de los trayectos.
