摘要: Laser induced fluorescence technique (LIF) enables the measurement of progress in mixing inside vessel. This is done by injecting a mixture an inert and reacting fluorescent dye into The serves as tracer for macromixing. changing its characteristics while undergoing fast chemical reaction with vessel content therefore shows micromixing indirectly. concentration fields dyes are measured simultaneously arbitrary plane using two-colour LIF-technique. Areas detected calculating local degree deviation from fields. Low Reynolds number measurements Rushton turbine show better macro- injection closer to stirrer shaft compared position centre main vortex.
