Isothermal Mixing

The laminar isothermal mixing of a viscoplastic fluid is considered in the absence of any free surface and when the material can be modelled using a Bingham constitutive equation. The material is mixed by a rotating cylindrical tank and a fixed anchor impeller. A two-dimensional numerical simulation is performed with a finite elements method. The effects of viscoplasticity and inertia are related to an Oldroyd (Od) and to a Reynolds (Re) number. Stream lines, vortices, yield surfaces and power consumption are shown and analysed depending on the value of Od and Re parameters.

Side-entering agitators are the main mixing system in the process of petroleum blending. Based on the three-dimensional gasoline components mixing model, the incompressible Reynolds equation is selected as the momentum equation and the algorithm of SIMPLE is employed to simulate the flow field of three side-entering agitators. In the unsteady multiphase flow, moving mesh and the standard k-ε turbulent model has been employed to get the mixing time. The results show that the model of side-entering agitators exists low-velocity zones, which are like structures of vortex in the central regions of blending tank, and the mixing time is 33.7s.
