Abstract Simplified three-dimensional models of glass-lined agitating reactors, which are commonly used in the chemical engineering industry, were established by UG (Unigraphics) in this paper. The models were then imported into Gambit for meshing and finally the Fluent simulation was conducted and analyzed on the flow characteristics in the agitator under different rotating speeds, working fluids and agitating forms. The results indicated that the rotating speed had little influence on the distribution of flow speed and pressure, However, the fluid speed and the pressure on the surface of glass-lined jacket of the thermometer increased with the rotating speed. Flow field showed different characteristics when the working fluid was changed. The pressure on the surface of thermometer was lower when larger viscous fluid was used because its field diffusion rate was relatively poor (diesel vs water). Taking the three different types of mixer(paddle type, impeller type and frame type) into account, the diffusion of the fluid speed for impeller-type mixer was better than that for paddle-type. In addition, it should be noted that the fluid speed distribution was the most uniform for frame-type, nevertheless, the pressure on the surface of thermometer jacket was significantly higher than that of the other two types of mixers.
