coal gasification

I am engaging in chemical engineering and just a beginner of CFD. My project is to simulate coal gasification pilot plant by Fluent6 code. I believe Fluent6 can be equal to it but I can find no way out.

The pilot plant is similar to Shell gasifier used to produce syngas, but the four or more nozzles are at the upper portion of the pilot plant. The fuel is pulverized coal or water-coal slurry and the oxidizer is pure oxygen. The pilot plant is operated at 40 atm and above 1300íŠ.

I am trying using Mixture Fraction/PDF approach to solve the gaseous turbulent combustion and Discrete Phase Model to describe particle phase motion, but the result is in a complete mess.

Can you give me some advice about my project?

Any responds will be highly appreciated. Thank you.

Re: coal gasification

I have only one suggestion... read and read a lot about your case, the models that you are going to use before running the first simmulation. This will give insight of how to run your case.

I work a lot with the DPM model and belive me it took me almost 6 months to get familiar with it

Best regards
