- Differenting and applying different approaches to modeling
- Simulating laminar mixing processes using Ansys Fluent
Description
Mixing is an important operation in many industrial processes, which always involves trade-offs between uniformity, product quality and cost. Process development engineers are faced with the task of either optimizing the design of existing mixers or devising stirring apparatuses that are tailored to specific mixing processes. Laminar mixing of highly viscous fluids result in particular challenges. This training course involves studying firstly the basic principles of designing industrial mixers and then also the main approach to assessing and improving mixing processes using Ansys Fluent. You will get to know a variety of Ansys-Fluent-based modeling techniques that can be used for designing, analyzing, and optimizing stirrers (both turbulent and laminar mixing). Multiple reference frame (MRF), sliding mesh and the tracer technique for assessing mixing performance will be covered as well. After an introduction to the rheology of mixing and stirring processes, we deal with the analysis of laminar mixing processes.
Several practical Ansys-Fluent-simulation-based workshops help to apply and consolidate your newly acquired knowledge. This training is aimed at CFD users and engineers involved in the design, assessment, and control of mixing processes in the chemical, petrochemical, and pharmaceutical sectors, spheres of water treatment and the food industry.
