Computational Fluid Dynamics is an attempt to solve the Navier-Stokes equation in mixing tanks. The outputs from these programs are so pleasing to engineers that they are often referred to as Colorful Fluid Dynamics. Many call CFD for mixing CFM, or Computational Fluid Mixing. At Mixing XIX CFD was coined Confusing Fluid Dynamics. A recent visitor made us aware of yet another acronym: Color For Directors!

This CFD represents a mixing time experiment using a 45o down-pumping pitched bladed turbine (PBT). The fluid to mix is spread out upon the base of the tank at the beginning. Click here to see a mixing animation and a detailed description of the conditions in high resolution. Caution: This is a high resolution animation. The download time will be about: 41 minutes on a 28.8 kBaud modem 21 minutes at 56 kBaud 10 minutes for an ISDN line 46 seconds over a T1 line

We have one of the best CFD (CFM) experts in the field on our team. We use the fastest and most accurate CFD software available (ACUSOLVE). We have created a special user friendly layer specifically addressing
dynamic mixing in horizontal or vertical tanks, cylindrical, rectangular parallelepiped (box) or spherical
dynamic mixing in pipes (also known as pipe mixers, inline mixers, inliners)
static mixers in pipes (also known as static mixers, Kenics® mixers, SMX®-mixers)
Rotor-stator mixing (also known as high shear mixers, dispersers)
(see below for more details on our CFD package)
CFD can be intimidating. Done correctly, CFD can replace experimentation. But what do all those lines and colors mean? Are the inputs meaningful? Are comparisons made at proper boundary conditions?

What conclusions should we make from these outputs? Post Mixing has the capability of getting CFDs or CFMs done in mixing tanks, columns, pipes, static mixers and other relevant reactor configurations. We can also have a look at your CFDs and describe to you what they are trying to convey. Don't draw the wrong conclusions from CFDs or CFMs. Have an expert take a look at them. We have access to one of the best experts in the field.
Computational Fluid Dynamics, or in this specific case, Computational
Fluid Mixing
is a very powerful tool when experimentation is either not possible, dangerous,
or too expensive.
Ask Post Mixing for a quote on CFD experiments for your process and reactor. We are not limited to mixing tanks. We can also do static mixers and mixing in pipes, etc. and even fun subjects like mixing honey in your mug of tea. The download time will be less than 2 minutes.
Have a look at some of the other CFD services we offer. There may be other uses of CFD that you have not yet considered.

It is important to have good reliable CFM or CFD software within which you can have substantial confidence relative to the physics of the process. Then you can accomplish a lot of virtual testing on the computer, before committing that design change to expensive real experimental testing and equipment costs. This saves you much time and money, as well as providing a better quality end product.
