Or you contracted with someone to do the CFDs for you.
Or you could have us do the CFD for you.
Have a look at an animation example.
Just because a computer program has printed a converged result on paper or a full
featured animation, doesn't mean that it has to be right. Does it look right? How do
you know? And if your CFD does not converge, do you know what that can mean? We do!

Did you know...
... that we can also determine fluid forces on baffles, baffle plates, shafts,
impellers and the tank (or vessel) walls using Acusolve CFD?
To design an agitation system  tank, shaft, impellers, and baffles (or
baffle plate)  each component must be built strong enough to withstand the fluid forces generated by the
impellers. Many calculations and programs are based on conservative hand waving ideas based
on the torque on the impeller shaft times some multiplier. This really isn't necessary anymore.
The Acusolve CFD program that we use, can accurately determine the fluid forces on baffles,
shafts, and the tank walls! Contact us if you would like a quote to determine the fluid forces
of your mixing system.
... that we can determine the power
number Np and flow number Nq using Acusolve CFD?
Most other programs require finetuning of the parameters to get meaningful power numbers.
It was mentioned over and over again at the 2003 Annual AIChE Meeting in San Francisco.
Not with Acusolve! The only parameter to change is the level of descritization. We have
verified the use of Acusolve for the Process Intensifier Study in standard tanks. Another
example is for a continuous flowthrough system: the mixersettler SXpumper.
... that we can determine pressure
drops and the dimensionless head number Nh?
Determining the pressure drop is easy. Have a look at
the pressure drop and the
pressure distribution in the pipeline of pipe mixers . We can also do this static mixers,
such as the Sulzer SMX and the Kenics mixer. Since the head number, Nh is so important for
pumper mixers for solvent extraction (SX), we can extract the
pressure drop information to
form the head number.
... that we can determine
 Flow patterns (Newtonian and nonNewtonian fluids)
 Free surface modeling (draining, filling, vortexing)
 Dead zones

Residence time distributions

Shear rate distributions
 Impeller design optimization (you should see the effect of a
5 degree change in the rake angle of a propeller)
 Feed pipe optimization
 Jet mixer nozzle orientation optimization
 And more
Key Benefits

 We have been analyzing CFD outputs for years.
 We can assist you to set up the experiment to verify the CFD outputs.
 We can do the CFD for you with great accuracy.
