studentFLUENT - Tutorial Library - Mixing Tank

Schematic of mixing tank impeller.

The purpose of this tutorial is to illustrate the setup and solution of a 3D turbulent fluid flow for periodic section of a mixing tank.

Mixing is a very crucial unit operation in process industry. The efficiency of mixing depends on the type of agitator that will provide the required level of mixing in as short time as possible. Mixing time is usually the critical parameter in determining the efficiency of an agitated system. A CFD analysis yields values for species concentration, fluid velocity and temperature throughout the solution domain. This allows engineers to evaluate alternative designs and choose the optimum configuration.

In this tutorial you will learn how to:

• Read an existing mesh file in FLUENT.
• Check the grid for dimensions and quality.
• Change the material properties and units.
• Set up boundary conditions for a moving fluid and wall zone.
• Set up boundary conditions for a periodic zone.
• Specify the solver settings and perform iterations.
• Create iso-surfaces and judge convergence by monitoring integrated quantities.
• Display the results over entire domain.
