A method of numerical analysis of three-dimensional flow behaviour of highly viscous pseudoplastic liquid in a stirred vessel was established. The proposed method is based on the simultaneous relaxation method for velocity and pressure in the frame of the finite difference method (FDM). Numerical analysis of the Newtonian fluid is applied to the non-Newtonian one, in which the viscosity constitutive equation is the three-parameter Ellis model. The developments of the circumferential velocity distributions on the radial axis and of the circulation flow with time are presented in this analysis.
The reliability of this numerical method was verified by the good agreement of the simulation results with experimental values by means of an image sensor velocimeter.
