中文摘要	Mixing, achieved mostly by mechanically stirring, is one of the most important unit operation processes in chemical and allied industries. The problem of designing and scaling-up stirred tanks has been tackled mainly by means of semi-empirical methods. Measurement and numerical simulation of viscous fluid in a stirred tank is still insufficient and further development is needed. In this paper, computational fluid dynamics (CFD) simulation and digital particle image velocimetry (PIV) measurement have been carried out to study the flow field of viscous fluid in a stirred tank agitated by a four-blade Rushton turbine. The working medium is the mixtures of water and glycerine with various concentrations. The results show mean velocity, turbulent energy, vorticity and pumping capacity of the fluids as well as the flow patterns change with the fluid viscosity. The commercial code of CFX4.4 with sliding grids was used to simulate the flow field. The CFD simulations were compared with the experimental PIV data. The result shows that the CFD simulations reflect the flow of the viscous fluid in a stirred tank.
