Optimization of Split Volute in the Double Volute Mono Set System Using CFD Analysis

Abstract

Recently most of the research problems focused on Single volute centrifugal pump and optimize the certain level of parameters such as number of impeller blades, angle and profile of the blade etc. that leads to improve the performance of the centrifugal pump [1]. Some of the authors conduct the research to reduce the radial force and noise level by implementing double volute centrifugal pump with fixed split structure for improving the performance of the Centrifugal Pump [2], but efficiency and head is dropped in the system at certain level of variation in radial force and noise. From this study, objective of this research paper is to reduce the radial force and noise level without sacrificing the efficiency and head of the Centrifugal pump. Existing single volute pump operate under constant speed (2800 rpm) has been taken for analysis and it consists of 6 vanes with forward curves impeller. This research mainly reduces the radial force by optimizing different position of split volute using CFD approach in order to improve the noise reduction in the double volute region. Numerical simulation of the existing pump also calculated by using CFD Technique and Investigation on Experimental analysis of existing centrifugal pump also done in research Laboratory. In this research, Optimization of split volute found the best way to reduce the radial force in the double volute pump. Different model can be simulated by using ANSYS-CFX to find the optimum position of split volute mono set centrifugal pump in order to develop uniform pressure in the volute region and reduce the radial force and noise of the Centrifugal pump.
