An impeller, according to present invention which consist of hub and at least one blade supported by the hub . In this study, turbulent flow fields in a vessel stirred by a lily impeller will be investigated. The resultant turbulence will be numerically predicted using Computational Fluid Dynamics (CFD). Turbulence models will be developed using ANSYS solver. The Lily Impeller will be designed based on the original design of Jay Harman, by making changes on its parameters like length/ height of Impeller, angle of blades and also number of blades. We will simulate the impeller action in the vertical and horizontal planes of the stirred fluid volume. Velocity profiles generated from the simulations will be used to predict and compare the performance of the different lily impellers with different parameters and most optimum designs will be finalized. To validate the Computational Fluid Dynamics (CFD) model, the simulation results will be compared with experimental results from existing work and most satisfactory design will be choosed. The final impeller will be able to provide better turbulence characteristics that would improve the quality of mixing systems.
