Abstract
Abstract: Single-blade sewage pumps with two different geometries are simulated numerically using two flow-solver packages, a University-developed FINFLO solver and a commercial CFX-TASCFlow. Both low and high Reynolds number approaches are utilized with k-ε and k-ω turbulence closures. Results are compared to the experimental data provided by Grundfos A/S. Main result: Pump head, efficiency and torque are obtained from the simulated flowfield. Wall-function approach under-estimates the head and the torque and over-estimates the efficiency. Low-Reynolds number simulation under-estimates all the values.Description
