LAMINAR MIXING FLOW IN A STIRRED VESSEL

Abstract

Using finite element method we study the transient motion of fluid particles in a 3D cavity, when the fluid is incompressible viscous and with uniform density. The fluid is mixed under the action of four-blades turbine that is simulated by a velocity function. The mixing quality of the fluid is studied qualitatively, by visualization, and quantitatively, by measurering the indices of diffusion and dispersion.
