Effect of Geometry on the Turbulent Jet in Convergent Ducts Using Computational Tool
Praveen K. Kasare,  Pankaj Mishra,  Veerendra Patle
Geometrical parameters to obtain the contraction shape that produces uniform turbulent jets have been studied numerically and experimentally over several decades. This paper review the several studies done by researchers in field of fluid flow through various shaped ducts. These numerically and experimentally studies aimed to suitable nozzle contraction design and optimization. The analysis provides that the equation of third order polynomial profile gives uniform mean velocity profile. Reynold stress Model(RSM) model provide better results for mean velocity profile and turbulence intensity. Computational fluid dynamic study with Shear Stress Transport (SST – k–x) model for rectangular cross section achieves the recommended contraction ratio and maximum uniformity. An important observation comes out from review, most authors provide qualitative criteria only based on acceptable non- uniformity and avoidance of boundary layer separation to select contraction profile and none of them had determined the optimum profile within the same family group of profile.
