Mixing is most widely observed phenomena in nature and it is also important for food industry, department of chemistry, and so on. Effective mixing in stirred tank make good product and high productivity in many cases. But quantitive data about its behavior in stirred tank is rare.
In this experiment a study on simultaneous measurement of flow pattern in stirred tank using PIV/PLIF is carried out. Instantaneous velocity fields and corresponding concentration fields is acquired. Through statistical processing some mixing characteristic- two time scale, ring vortex- in stirred tank has been identified.
It is noted that baffle in stirred tank can progress mixing efficiency. In case of baffle attached experiment, there exist several vortex disturbing inactive region, and this make flow more complex, boundless streamlines.
