coal/petcoke gasification
 

I am trying to simulate the coal/coke gasification in an entrained bed gasifier. I understand that as the kinetics for coal gasification reactions are not available in FLUENT, so we have to write UDF's. Can someone help me out regading which macros I should use. I was thinking of using DEFINE_DPM_LAW and DEFINE_DPM_SOURCE. But I am not sure about the structure of UDF.

Any help will be highly appreciated.:)

Thank You.
