Experimental results for massive blowing studies.

Previous work on the problem of massive blowing is described. A technique for visualizing the streamline separating the blown gas from that of the oncoming stream is developed, in which a chemiluminescent reaction along the separation streamline appears as a yellow glow and is easily photographed. Data for a variety of aerodynamic shapes over a wide range of flow conditions were obtained. A major result is that the separation streamline is essentially straight for a wedge- or cone-shaped model. Pressure distributions measured on the surface of wedge and cone models indicate that the pressure decays from high values near the leading edge of blowing to low values near the trailing edge.
