This article concerned the mixing of high-viscosity fluids using close-clearance impellers in a cylindrical tank (caustic soda and water). This investigation employed a numerical model to evaluate the performance of three distinct impeller designs at rotational speeds of 10, 20, and 30 rpm. The analysis concentrated on parameters indicative of mixing efficiency, including color dispersion, vector movement of the mixed material, temperature gradients from the tank wall to the center, and the average temperature within the agitator tank. Results indicated that the ribbon impeller operating at 30 rpm achieved the highest average temperature (53.69℃) across all measurement points within the mixing vessel compared to the other impeller configurations. This finding suggests that the ribbon impeller design is most effective in promoting optimal mixing. Additionally, the heat distribution within the tank exhibited a high degree of uniformity, which contributed to consistent vector movement of the mixed material. Furthermore, the temperature gradient, representing the average temperature variation from the tank wall to the center at each depth, was most pronounced with the ribbon impeller design.
