Design and Optimization of a Centrifugal Pump for Slurry Transport Using the Response Surface Method

Since centrifugal pumps consume a mammoth amount of energy in various industrial applications, their design and optimization are highly relevant to saving maximum increasing the system’s efficiency. In current investigation, pump has been designed optimized. The study carried out for specific application transportation slurry at flow rate 120 m3/hr head 20 m. For process, multi-objective genetic algorithm (MOGA) response surface methodology (RSM) have employed. process is based on mean line pump. It utilizes six geometric parameters as variables, i.e., number vanes, inlet beta shroud, exit hub blade draft, Rake angle, impeller’s rotational speed. objective functions employed power, hydraulic efficiency, volumetric this reference, five different software packages, ANSYS Vista, DesignModeler, software, CFX, were coupled achieve optimized geometry. Characteristic maps generated using simulations conducted 45 points. Additionally, erosion was predicted 3-D numerical under conditions. Finally, transient behavior pump, being highlight study, evaluated. Results suggest that fluctuation local pressure stresses cases correspond phase angle 0°–30° casing turn corresponds rates region.
