Abstract

Abstract: The fluid dynamics and the gas-liquid distribution character in a three-layer stirred tank reactor with 2KSX (four wide blade propeller type stirrer) and PDT (parabolic disc turbine) were analyzed with the MRE (multi-reference frame) method based on Euler-Euler and population balance models. The total and local gas-hold were calculated. The conclusions show that: axial flow was produced by double stir upper KSX with radial flow produced by the third layer of PDT, gas-hold was improved with double-upper-layer stirrers axial driven and the lowest stirrer axial driven, gas-hold increased with the stirred time going on, which would not be extended with stirring with the time more than 26 s.
