Hydrodynamic Study of Turbulent Fluid Flow in an Axi- Symmetric Duct with Crescent

In this article, the fluid flow analysis in an axi-symmetric duct with and without crescent has been studied numerically. Fluent 6.3 based on finite volume method have been used to analyze the flow problem. The parameters varied are non-dimensional crescent length 1 ( / ) C L  S R of 0.9 to 0.5 and Reynolds number of 7.5X104 to 3.5X105 respectively. An experiment has been carried out in a straight sudden expansion pipe without crescent for same Reynolds numbers. The numerically achieved results have been compared with the experimental results thus obtained for different Reynolds numbers for the case of without crescent only. The results have been found to match reasonably. The main objective of this study is to find out the friction factor in an axi-symmetric sudden expansion duct with crescent. The results show that the friction factor decreases with increase in Reynolds number and crescent length respectively.
