Liquid flow in chemical agitating equipments goes with the distinct heat transmission process .Because of the complexity of stirring flow and difficult measurement of the temperature distribution , adopting experiment method has a certain limitation. Utilizing computing flow hydrodynamics software (CFD), a standard κ-ξ turbulent model was adopted .Under the non -isothermal and astable condition, three -dimensional flow field and temperature field' s distribution in agitating trough was analyzed in the mixing process of turbine agitating paddle .The results show that when the propeller blades rotating , high -speed jet flow appears in the impeller area .Radial jet flow , carrying surrounding fluid in the process of flowing , bounces tank wall , which ejects in radial direction and becomes two par ts .Near the upper side and low er side of impeller forms two recycle vortexes.With the increase of the stirring time of propeller blades, the temperature of fluid in the tank tends to be even gradually .But six low temperature areas appear the bevel upper position with 6 propeller blades.A majority energies produced by the propeller blades are used up in the eduction flow area near the propeller blades.
