Effect of Divider Plate Trailing Edge Shape on the Mixing of Parallel Flows.

Abstract

The objective of this effects is to investigate the mixing process as characterized by velocity and turbulence data. The effects of divider plate trailing edge modifications upon the mixing of parallel co-flowing air streams is also examined. Five divider plate trailing edge configurations were tested at velocity ratios from 0.3 to 1.0 with a maximum velocity of 300 ft/sec. A two element hot film anemometer was used to determine the flow velocities and turbulence. Wake growth rate determined from velocity and turbulence profiles was the primary indicator of mixing. The modification which extended beyond the original plate thickness produced the highest wake growth rates and was the best mixer. No reliable correlation between maximum turbulence and mixing ability was determined. (Author)
