This study investigates the impact of turbine impeller blade geometry (rectangular, circular, triangular, and star-shaped) with identical cross-sectional area and volume on hydrodynamics in a bioreactor using ANSYS CFX. Flow velocity and shear strain rate distributions were analysed to assess mixing efficiency. The rectangular blade exhibited the highest flow velocity but also elevated shear stress, potentially harmful to sensitive cultures, while the triangular blade showed lower shear stress, suitable for delicate microorganisms. Results highlight the importance of blade geometry optimization for enhancing biotechnological processes.
