Quelques réflexions sur les hydrocyclones en séparation

l'hydrocyclone peut fonctionner en séparateur ou en mélan­ geur. Ce comportement particulier explique, sans doute, pourquoi l'hydrocyclone n'est pratiquement pas utilisé industriellement pour la séparation liquide-liquide. Nous verrons enfin comment, en tenant compte des servitudes de fonctionnement de l'hydrocyclone, nous avons

Effects of inlet size on separation flow field inside hydrocyclone

2013年7月1日  In this sense, the flow field with smaller inlet is prone to better separation. However, smaller inlet size facilitates the formation of secondary vortexes and enhances the entrainment of fluid by the injected flow, which may hamper the separation. Thus, the cut-off size will not always decrease with the reduction of inlet size.
