Abstract

Schlieren photography is used to observe the steady state and transient behavior of axial and vectored flow in a two-dimensional thrust vector control nozzle in two different wind tunnels. It is shown that video recording in conjunction with a schlieren optical system is a convenient and useful means of observing transient flow conditions. To illustrate the video capability, the flow response in input variations in the two-dimensional confined jet nozzle is made visible and recorded by the schlieren/video system. The method can be used in wind tunnels in general.
