i wanted to know if solidworks flow simulation is capable of simulating cyclone separators, i'm looking for a way to simulate a cyclone process to classify mineral powders according to density.
Thnaks Joe. i will give solidworks flow simulation a try.
i found out that wide angle or 'water only' cyclones are used to sort particles according to density. does anyone know any design guidelines for this type of cyclones?
does flow simulation support RSM; Reynolds Stress Model (turbulance model) ?
i've seen papers which prove, RSM is the most appropriate model for this type of problem.
The turbulence model used in flow simulation is the K epsilon model.
Where turbulences are averaged. Sometimes we talk about Reynolds Averaged Navier Stokes equations (RANS)
We have a customer in Italy, Modutech, who does cyclone separators and Alessandro wrote to me after I inquired about his experience. He says, "in my opinion the K-e model works perfectly and the behavior in Cyclone I sent you last year is very accurate."
You can see some pictures of his results at the following link: Modutech
I have used Flow Simulation 2009 to evaluate the flow in a helical (very similar to a cyclone) separator that separates oil from refrigerant vapor in a refrigeration system. With the understanding that Flow does not compute flow patterns of two phase substances, I used a particle study to understand the separation of the oil from the refrigerant vapor. The results are credible, but I do not have the capability to validate that claim because field temperature measurements of the vessel wall are the most readilly available parameter to validate the study. Unfortunately, Flow does not compute the thermal transfer properties of the particles. If Flow were able to further compute the thermal effect of the injected particles it would be much more useful as a design tool that can help interpret results of actual simulations. The thermal effects of particles provide the most useful method of measuring the efficiency of this kind of separator in an actual field test.
Flow needs to provide the capability of calculating the thermal effect of particles as a third stage computation so that evaluation can be made of actual field tests of this type of separator, as well as many other types of devices. And this also suggests that Flow should be able to be "calibrated" to make the computer model match the test model. This way the results of design changes to the separator can more accurately be predicted.
While the flow patterns predicted by Flow are believable, the particle behavior is believable, the program does not provide the utility to validate field measured results. I think this essential to consider Flow a true design tool.
