[11 Dec 2013] Mixing tanks are heavily used in process industries where high-speed agitation and rapid mixing are necessary. While impeller-stirred tanks promote efficient mixing, the highly three-dimensional flows pose several meshing and simulation challenges. We will address these challenges using a generic, baffled tank stirred by a Rushton turbine. We will demonstrate how to use Pointwise to generate high-quality unstructured meshes suitable for steady-state moving reference frame calculations. Additionally, using Pointwise's recently-updated native interface to OpenFOAM, we will define both the boundary conditions and zones necessary for OpenFOAM inside Pointwise. That's right – Sets are no longer necessary to define a Zone! Lastly, we will describe how to prepare an OpenFOAM case for a moving reference frame calculation and compute the power necessary to drive the Rushton turbine in a single-phase flow.
