Recently, a tall stirrer tank with narrow space has been requested for effective use of land space. A new stirrer system using draft tube was demonstrated for satisfying the above request. Experimental works and numerical analysis were carried out to reveal the performance of mixing operation under low power and low rotational speed. We also confirmed shearing force of paddles were lower than conventional stirrers for applying as bioreactor. The results show that the uniform flow velocity distribution in a tank was successfully achieved by adding the adequate size of guide ring. The effect of guide ring on mixing time and the shearing force in the draft tube system were also revealed.
