Mixing of Two-Component Flow in a Simplified Stirred Tank with Cellular Automaton Method

A Study on Liquid-liquid Mixing in a Stirred Tank with a 6-Blade Rushton Turbine

The turbulent flow field generated in a baffled stirred tank was computed by large eddy simulation (LED) and the flow field was developed using the Sliding Mesh (SM) approach. In this CFD study, mixing times and power number have been determined for a vessel agitated by a 6-blade Rushton turbine. The predicted results were compared with the published experimental data. The satisfactory results ...

Evaluation of two lattice Boltzmann methods for fluid flow simulation in a stirred tank

In the present study, commonly used weakly compressible lattice Boltzmann method and Guo incompressible lattice Boltzmann method have been used to simulate fluid flow in a stirred tank. For this purpose a 3D Parallel code has been developed in the framework of the lattice Boltzmann method. This program has been used for simulation of flow at different geometries such as 2D channel fluid flow an...

Heat Transfer Correlation for Two Phase Flow in a Mixing Tank

Mixing tanks equipped with mechanical stirrer are broadly applied in chemical and petrochemical industries, due to their variety of industrial process requirements. In this study, helical single blade mixer was designed applying CATIA and then mixing of fluid and solid particles, in a tank with this agitator was examined by OpenFOAM. For velocity distribution in the mixing tank, continuity, mom...

Compartment Mixing Model in a Stirred Tank Equipped Dual Rushton Turbine

Comparison of mixing between single- and bubbly two-phase systems in a Rushton stirred tank

Mixing is a widely practiced operation to effect distribution, intermingling and homogeneity of matter. Stirred tanks with different geometries (such as in main container tanks, impellers, baffles, etc.) are also widely used to mix different materials. The forces applied by impellers develop overall circulation or bulk flow. Superimposed on this flow pattern, there are turbulent eddies and also...
