| dc.description.abstract | This Master's thesis project presents a numerical investigation, using CFD simulations, of the hydraulic behavior of a miniaturized magnetically coupled centrifugal pump manufactured via 3D printing. The primary objective was to accurately reproduce and validate the pump’s hydraulic performance (pressure rise and volumetric flow rate) by comparing simulation results with existing experimental data. Three distinct impeller designs—radial, forward-curved, and backward-curved—were analyzed at various rotational speeds. The adopted methodology involved numerical modeling of the pump geometry, followed by the application of a poly-hexcore meshing strategy. Simulations were conducted under steady state conditions using a pressure-based solver with the k-ω SST turbulence model. Boundary conditions were carefully defined to closely replicate the experimental setup. CFD results demonstrated strong agreement with experimental data, confirming the superior performance of the backward-curved impeller (Type 3) in terms of flow rate and pressure head. Although the model exhibited a slight tendency to overestimate performance, the observed discrepancies remained within acceptable limits for numerical validation. | |
