As in any Casting process, Gravity die casting process has a significant rejection due to defective casting process. There are many factors which affects these defects in the component. One of the main reasons is the improper design of the component itself. If the component geometry is properly studied and analyzed, it can effectively reduce the defects arising in the casting of a component. Design For Manufacturability (DFM) during the component design stage eliminates the need for tool correction and re-tooling at the later stage of product life cycle which will indirectly increase the cost...

Hydraulic efficiency of the centrifugal pump is mainly depends on mass flow rate, Head and RPM. Finding the best combination with the above said parameters and the best geometry of the pump is possible by using three dimensional CFD simulations.For designers, prediction of operating characteristics curve is most important. All theoretical methods for prediction of efficiency merely give a value; but one is unable to determine the root cause for the poor performance. Due to the development of CFD code, one can get the efficiency value as well as observe actual behavior and the root cause for...
