Kunal Gharat,Pawan Gajare,Snehal Murumkar,Parth Gandhi,Amol Mangrulkar To Investigate Effect of Geometrical Parameters on Performance of Low Specific Speed Centrifugal Pump Using CFD Abstract: Effect of blade thickness ratio and geometry of the blade at the outlet of impeller on the performance of low specific speed centrifugal pump was investigated. The type of fluid to be pumped (water) and its properties were determined based on application of pump. Based on this, the type of impeller was decided as closed type impeller. The range of number of vanes was also decided based on fluid properties from literature survey. In CFD,This model was then simulated for operating conditions of a low specific speed centrifugal pump.

INTRODUCTION S TUDIES by the United States Department of Energy/Lawrence Berkeley National Laboratory and the European Commission show that more than 20% of the global motor electrical energy consumption is consumed by pumps. [1]This illustration shows that pumps consume 22% of the industrial energy consumption, hence the area which has great energy saving potential. Centrifugal pumps are the rotary machines in which fluid is pressurized or pumped majorly due to velocity changes that occur between inlet and outlet. In short, the kinetic energy of the fluid at inlet is converted into pressure energy at outlet. This pressure energy in turn helps in elevating fluid to the desired height. A centrifugal pump comprises an impeller rotating at a high speed within a stationary casing. The input of centrifugal pump is the mechanical energy imparted by the prime mover through the impeller. In a centrifugal pump the liquid is forced by atmospheric or other pressure into a setoff rotating vanes. The parameters affecting the performance of pump are type of impeller, number of vanes, blade exit angle, volute geometry. The flow in a centrifugal pump is very difficult to visualize. Computational fluid dynamics is the analysis of systems involving fluid flow, heat transfer, and associated phenomenon such as chemical reaction by means of computer based simulation. Computational Fluid Dynamics is an effective tool that can be used to design machine. The project thus employs CFD as a…show more content…
