Mixing of Water in a Flat Bottom Mixer

Application ID: 14597


This tutorial example simulates the flow in a flat bottom mixer containing, agitated by a pitched four blade impeller, where the fluid is water, and flow is assumed to be turbulent. The flow in the mixer is modeled using the k-ε turbulence model, and a time-dependent simulation corresponding to 30 revolutions of the impeller is performed in order to reach the operating conditions of the mixer.

When postprocessing the results, the self-similarity of the axial flow along the baffles is analyzed. In agreement with literature, the normalized velocity profiles at different axial positions are found to be self-similar indicating that the flow in this region resemble a three dimensional wall jet.

This model example illustrates applications of this type that would nominally be built using the following products:
