Numerical Simulation of Gasoline Blending in a Cylindrical Tank Agitated by Side-Entering Agitators

Abstract:

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.
