Abstract

In recent years there has been considerable interest in the active control of fluid flow phenomena. Applications include separation control, drag reduction and lift enhancement. The present study is concerned with flow separation and reattachment, and considers the case of flow through a 10o plane diffuser, studied experimentally by Masuda et al (1994), where the control is provided by a periodic injection/suction upstream of where the flow would separate under stationary conditions. Results are reported using the two-equation linear k- model of Launder & Sharma (1974) and a two-equation non-linear k- scheme (Craft et al., 2005),
