Abstract
This study presents a numerical analysis of mechanical pumps' function when working with Fluids that are not Newtonian. The complex rheological properties not Newtonian fluids, which are different from Newtonian fluids, have a significant influence on pump performance. Shear-thinning and shear-thickening properties are among these attributes. Using computational fluid dynamics (CFD) simulations, key performance parameters like head, efficiency, and power consumption were investigated under different flow conditions. The results demonstrate how fluid rheology affects internal flow patterns, pressure distribution, and overall pump efficiency. This study provides useful information about how to optimize centrifugal pump designs for industries that deal with non-Newtonian fluids, such as chemical manufacturing, food processing, and pharmaceuticals. The non-Newtonian fluids harm on the properties of an engineered centrifugal pump to pump water 40 l/min and 3300 rpm. in terms of numbers. A number The investigation was conducted using the Computational Fluid Dynamics technique. The analyses were conducted using water and three distinct non-Newtonian fluids generated from Carboxy Methyl Cellulose (CMC) solution: CMCs of 0.4%, 0.3%, and 0.2%. The assessments seemed conducted using rotor speeds of 3300 rpm and 1400 rpm with flow rates between 10 and 80 liters per minute. According to the findings, the pump performed better 3300 rpm with non-Newtonian fluids as opposed to water as contrasted as high as 1400 rpm.
