heal.abstract	During the last decade, efforts for simulating active flow control behavior by the use of pulsating jets have multiplied. In the present work, a URANS is used mostly for simulation, where the resulting flow characteristics can be reproduced with fair but adequate accuracy for engineering applications. This computational tool provides information concerning the effect on the flow, of the flow control. An additional computational tool is introduced, that of flow stability analysis, which allows to optimize the frequency and the position of the actuators (here pulsating jets). This tool will be developed through flow stability arguments. Both tools will be used within the context of the present paper and for reasons explained below, for suppressing only flow separation in internal flow cases. Once the computational tools are described/developed, they will be applied to a specific case. The optimization procedure will be demonstrated and discussed. © Springer Science+Business Media B.V. 2007.	en
