Flow Mixing Optimisation inside a Manifold using Computational Fluid Dynamics

This paper presents an analysis of fluid flow in a typical manifold. A commerciallyavailable Computational Fluid Dynamics (CFD) package has been used to analyze the flow pattern inside the manifold. Temperatureand velocity in whole fluid domain and mass flow rate in all the outlets in the manifold have been computed. Based on the preliminary results, a simple modification to inside of the main pipe of the manifold has been incorporated. The performance of the modified design has been compared with the original design from the point of view of average temperature and mass flow rate at the outlets. This simple modification has been shown to improve the uniformity of temperature and mass flow at the outlets, thus enhancing the efficiency of the mixing manifold.
