Numerical Investigation of the Active Flow Control of Jets

Obiettivo

The modification of global characteristics of conventional free jets with the objective of affecting flow direction, cross-stream spreading and mixing is of a considerable interest becuase of the relevance to a number of engineering applications, including thrust vectoring, improved combustion and reduced noise pollution. In this project the numerical approach will be used for further development of a recently proposed method of active flow control relying on an interaction between a primary jet and a smal l-scaled high frequency control jet. The main goal is the derivation of a 'simplified' computational model, capable to reduce significantly the enormous computational effort required by the fully resolved simulation approach. Such simplification is highly desirable for an efficient numerical investigation and for the incorporation of the numerical simulation approach in future improvments of the control method. Emphasis will also be put on clarifying the basic physical mechanism lying in the base of this ac tive contol method, i.e. on the interaction between a primary jet an a localized disturbance of large amplitude.
