Abstract
Windtunnel tests with cold jet nozzles do produce similar flow conditions and thus possibly the same results as hot jet nozzles when test specs are evaluated in locally similar Areas. The paper's scope is to show that this is especially the case for UHBR dual stream flow at acoustic test condition Approach in the location of the jet-flap-interaction region.
