My company is thinking of purchasing CFX for performing Hydrodynamic analysis. I want expert opinion on the the performance of this code. Any validation work along with tet results is welcomed

We use it to simulate turbulent gas-solid flow in CFB reactor, and we find in this field the code is not capable, for the physical model it provided is poor.

So if your work focus on this field, you must be cautious.

Dear Yu Zheng,

what kind of deficiencies have you found in the physical model for the simulation of turbulent gas-solid flow. I am using CFX for modelling fluidised beds.

Kind regards, Heiko

Hi there, I'm currently using CFX4.3 for modelling ship rudder flows and in calculation hull form drag. I've carried out some detailed studies into CFX4.3's performance compared with experimental data. If you're interested in my findings then let me know.

Regards James

I am also working on turbulent gas-solids flow in CFB. The phsical models provided by the code is not capable of modeling the flow, but you can add your own physical models to the code using user fortrans.

Are you using CFX4.2 or 4.3

I am using CFX4.3.

Hi James

I am interested in your validation results for CFX 4.3. We have been using CFX4 for several years for ship flow calcs and would like to see other results.

We are very interested in results for different models for turbulence as we are currently developing new models for CFX5

Thanks very much

Peter Bull

Dear Peter & James, We started using CFX recently for simulation of the flow past ships. We will particularly interested if you have some results with free surface modelling incorporated. Regards, Tanmay
