| Abstract | ||
| Theoretical and experimental investigations of discharge coefficient and jet deflection haw been made for holes having parallel flow to the plane of the holes with and without cross flow. In· the experimental investigation. geometric configurations studied were. circular holes. oval. rectangular and square slots. The main geometric and llow factors affecting the discharge coeffiecient and the jet deflection were studied. The geometric factors were. ratio of hole area to approach duct area ranging from IJ.Oh to IJ.h. slot aspect ratio ranging from I to 8. with a duct depth of 31. 7:; mm. The flow factors were. static pressure ratio ranging from I to 1.12. bleed ratio through the holes and approach velocity. The results of these investigations have been correlated with a dimensionless flow parameter incorporating both the geometric and the flow parameters. Good agreement has been achieved between theoretical and experimental results as well as between this work and the previous work within the range of investigation. | ||
