combustion of Aluminum particle in oxidant-rich ga
 

Hello,

Now I want to use fluent5.4.8 to simulate combustion of Aluminum particle in oxidant-rich gas. But I don't know how to solve it.

Do you have some cases about this?Would you like to give me some cases?

Thank you for your help.

Please refer, DPM(Discrete Phase Model), Species Transport, Reaction and so on......

MR LEE:

Thank you for your help.

There is an example about Pulverized Coal combustion in fluent5.4.8. There is C(s) species in prePDF material database.But There isn't Al(s) species in prePDF material database.How can I add new material.

1. Modify 'thermo.db'.

2.prePDF 3.1 or higher already has Al(S) in it's database.

Thank you for reply.

But I don't understand some data in'thermo.db',such as"62987"and "120186".if I add new matiral,which number should I give to this new matiral.

Thank you for your help.

Hi,

Those numbers are comments. 62987 means the fitting coefficients of this species was generated on June 29, 1987.

Mr Ken

Thank you for your reply.

Now if I want to add new material in prePDF,what do I want ot do excepting changing the data in file "thermo.db"?

Thank you for your help.
