Effects of Cross Jet on Turbulent Main Stream Flow in A Non-Circular Elbow – A Numerical Approach
Authors: , , , ,
Abstract: The performance of fluid transportation model through non-circular elbow ducts with wall mass injection in predicting the velocity and pressure fields is important in Industrial applications. The present work pertains to the two-dimensional numerical analysis of the developing turbulent fluid flow with uniform mass injection through the top wall of a rectangular elbow. A numerical experimentation using control volume formulation considering standard k turbulence model has been conducted to study different parameters like the velocity distributions, size and shape of the recirculation bubble as well as the friction factor etc. The size and strength of the recirculation bubbles generated in the bend regions are affected by the continuous entry of mass injected through the wall of the elbow. The results show that the velocity field, reattachment points, friction factor etc. are influenced by the side mass injection. The recirculation bubble has been observed to diminish in size by the injection of mass with corresponding changes in the velocity and the friction factors
