CFD Analysis of Agitator
“The use of computational fluid dynamics (CFD) modeling software has grown quickly over the last two decades based on the availability of increasing computing power. Commercial software can be used to predict flow patterns in both simple and complex geometries. The output from these models, when analyzed by a CFD engineer experienced in the field of fluid mixing, is an important tool in industrial mixing design.
Nevertheless, a clear understanding of fundamental fluid mechanics is required to properly use CFD. This includes applying 1) the correct fluid model to the situation (laminar or turbulent); 2) sound volume-meshing techniques; 3) the appropriate boundary conditions to the given geometry and 4) experimental validation of results. Thus, CFD is best handled by experienced engineers that understand the latest analysis tools and are well versed in mixing technology.
Mixers are modeled using either 2D or 3D CFD techniques. The first applies only to axi-symmetric installations, i.e., round tanks that are fully baffled, with a mixer mounted vertically on the center. Knowledge of the impeller outlet velocity profile is required for 2D modeling, which is obtained through experimental techniques such as laser Doppler velocimetry (LDV).
Ideametrics Private Limited is an industry leader in applying Computational Fluid Dynamics (CFD) techniques to the design of equipment. We have executed number of projects for CFD based reports validating product safety or illustrating shortcomings. Our reports are in compliance with design standards and can be made to comply with the multiple different registration guidelines.”
