Abstract
For a wall-reattachment amplifier with activated opposite control flow, we have not yet gotten sufficient experiemental data of reattached jet flow and a reasonable theoretical model. The investigation of flow behaviors in such a amplifier may be primitive for dealing with a signal transfer in the circuits using these ampliers, as well as flow behavior itself.
In this report, the above mentioned flow behaviors have been investigated by experiments using a large scale model and author's theoretical approach proposed already. The results obtained are summerized as follows:
(a) The relation between a relative control total pressure and a relative control flow rate, which has already known experimentally, may characterize the three interacting jet flows. This relation can be evaluated by author's theoretical approach.
(b) The relative switching control flow rate may be independed on the opposite flow and constant for a contacting-bothwalls switching, while for a terminatedwall switching such an independency is not valid. This can be explained by the reattached jet flow behavior.
