The simulation of mixing in a dough-hook mixer can be perfectly performed using NOGRID points CFD software. Mixing plays a vital role in the food- and chemical industries and is used in processes such as the dispersion of two or more liquid, powdery or gaseous components, deagglomeration to prevent lump formation, and the homogenization of mixtures.

Improve product performance and reduce costs

Mixing simulations help to better understand the flow behavior in an agitator, enable quick optimization of design and operating parameters, and reduce both production and maintenance costs.

Compute any agitator geometry with mixing simulation

NOGRID offers a wide range of rheology models including those commonly used in the chemical industry. Its unique capabilities for handling moving parts within the fluid domain make it possible to simulate virtually any agitator geometry and operating modes, such as

rotating and counterwise rotating agitator blades, possibly moving up and down periodically at the same time
overlapping operation ranges of moving parts as found in twin-screw agitators
free surfaces at inlets or for different fluid levels or for fast rotating agitators with high centrifugal forces

Benefit of very short computation time

One of the key strengths of NOGRID's meshless CFD software is the rapid preprocessing (no grid generation required) and its exceptionally short computation times, even for complex moving parts commonly found in agitators.

Capabilities of NOGRID points CFD software

NOGRID combines powerful capabilities for simulating free-surface flows and moving parts within the domain, resulting in the following advantages:

fully 3D computation solving the complete Navier-Stokes equations
easy and intuitive setup also for FSI (Fluid-Structure-Interaction) cases
freely definable material properties by equations or curves
evaluation of the mixing quality
open or closed domains including inflow and outflow areas (non-batch mode)
moving of the mixers in any direction

Nogrid's strengths

Particular strengths of NOGRID's fluid flow CFD software are the rapid preprocessing (no fluid grid needs to be generated, only the boundary mesh, inner finite points are generated automatically depending on User setting initially and during computation), and the outstandingly short computation time even for complicated cavities.

As you can see in the image below, the boundary of the geometry still requires a mesh to allow the interior finite points to detect the boundary. The boundary must therefore be meshed and the finite points inside are automatically generated during the simulation controlled by User specifications.

Easy and fast modelling: Build geometry, mesh boundary, setup the case and start computation

What is CFD from NOGRID?

CFD solves the fundamental equations that define the fluid flow process. With CFD software from NOGRID every engineer makes better decisions by predicting, analyzing and controlling fluid flow, heat and mass transfer or chemical reaction. By using NOGRID software for flow modeling you receive information on essential flow characteristics as for example flow distribution. Using it additional to testing and experimentation NOGRID software helps to improve the evaluation of your design – resulting in better construction and operation parameters, increasing planning security and money savings due to faster time to the marketplace for your product or process.
