Modular Mixer - Turbulent Mixing

This model provides you with tools to build a variety of mixers by combining two common types of vessels with two types of impellers. The mixers are baffled flat and dished bottom vessels with either pitched blade impellers or Rushton turbines. The model includes three examples using the Rotating Machinery, Fluid Flow branch with the frozen-rotor study type. The first example solves a laminar ...

Behavior of Power Law Fluids in a Mixer

This model shows how to use simulations to predict power numbers with Power Law fluids in a mixer. It simulates the behavior of flow in a flat bottom tank with a single four-blade pitched impeller. The flow was modeled as laminar and the frozen rotor approach was used to solve the discrete governing equations in one quarter of a baffled tank. The calculated power numbers were compared with ...

Non-Isothermal Flow in a 2D Mixer

This model illustrates the modeling of temperature distribution in a simplified mixer.

Mixing of Water in a Flat Bottom Mixer

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

This application is intended for the simulation of mixers equipped with axial or radial impellers. With a given geometry, the application computes the efficiency of the mixing process. The measure of efficiency is the eddy diffusivity, which gives the time scale of mixing of chemical species in the mixed fluid. The impellers can be of eleven different types each type with different variations, ...
