Paper Abstract

This research is part of a study of the behaviour of high-velocity gas jets,particularly as regards their acoustic behaviour and noise generation. As a step towards understanding multiple jet configurations we have investigated a 2-jet situation. 2-D nozzles were designed so that they could be mounted side by side and operated separately. The nozzles could be moved by a vernier control from a separation of several centimeters till they were adjacent. Vertical motion of one jet and some rotation was also possible. The photographic approaches included a stroboscopic/TV method from which video recordings and a film were made and single flash high-resolution photography. Observation were made on the cell structure, oscillation phenomena and the way the two jets interacted both acoustically and aerodynamically.
