Abstract
This report describes the work carried out in continuation of the preliminary tests on the use of splitters for flow control in a wide angle conical diffuser, already reported, and deals with experiments aimed at identifying the flow mechanism responsible for the success of the splitters.13; Flow visualisation tests revealed the existence of a larger-trapped vortex in each pocket of the eight-vane splitter in all cases where a stable diffuser flow with13; relatively uniform exit profile was achieved. The qualitative relationship between the splitter geometry, vortex location and the exit profile uniformity were established, and the effect of inlet flow turbulence was briefly investigated.13; For optimised splitter configurations, pressure loss measurements indicated that efficiency approaching 50% is attainable for the 38xB0; conical angle, area ratio 15 diffuser model tested.
