摘要:

Impeller power numbers in closed square vessels with/or without baffles and in closed cylindrical vessels with baffles were studied for impeller Reynolds numbers in the range between 75000 and 300000. A flat vertical blade disk style, a vertical blade open style and a 45° pitched blade open style impellers were used. A substantial reduction of power number is observed for all three impellers inside the square vessels without baffles in comparison with baffled cylindrical and square ones reaching up to 61 %.
