combustion of particle in fluent

Devy

Now I also use dpm for a solid combustion problem in fluent.My combustion model is such as:

Al(l)--->Al(g)

O2------>2O

Al(g)+O--->AlO

Al(l)+AlO-->Al2O

Al2O+O2---->Al2O2

Al2O2+O---->Al2O3(l)

Now I still dont'know how to track the product(Al2O3)particle trajectories.Mybe I take the product(Al2O3) as gas.

Now I want to use UDF to simulate the combustion of AL.There are so many DEFINE Macros for discrete phase model.Which Macros should I select,DEFINE_DPM_LAW or DEFINE_DPM_SOURCES ?

Do you have some cases about DEFINE_DPM_LAW and DEFINE_DPM_SOURCES? If you have,would you like to send me a copy?

Thank you.
