A Study on the baffle effect in a stirred mixer using simultaneous measurement of velocity/concentration fields

속도/농도 동시측정에 의한 회전교반기 내부 유동의 baffle 효과에 관한 연구

Simultaneous measurement of velocity and concentration fields in a stirred mixer flow using a combined Stereo-PIV/Planar-LIF technique is carried out. Instantaneous velocity fields and concentration fields represent the local flow characteristics. A baffle is perpendicularly attached to the Wall to remove inactive region which shows very slow dispersion. It is found that the baffle produces tip vortex and breaking the divided streamline, so that mixing efficiency could be increases significantly.
