Is there a specific model for gasification in fluent or do we have to use a UDF ?

Can anyone answer the "Invalid cp problem at a particular temperature in fluent"? It will be a great help?

Invalid cp problem occurs in my fluent window. If I change cp of one material then same error occurs due to other. Is it a problem of mesh? Or any other problem. Please Help.

Thank you for the answer sir.

But this thesis talks only about combustion part and not gasification.

Still it was helpful. Thank you very much sir.

Please, check this and try to contact with the author.

Sorry, I'm not providing an answer. I just want to say that partial oxidation or combustion with a great deficiency in oxygen is a "grey area" for even simple cases such as partial oxidation of methane into syngas without a catalyst.

As for as I know, the gasification is not included in the Fluent. Note that the gasification relates strongly to the the combustion mechanisms. It's not reasonable to include a model in CFD without the mechanisms. If you really need to do so, you should find the mechanism you need and import it in your Fluent model.
