Reply To: Energy source term related with chemical reaction in UDF

[Bruce Zhou]

Thanks for your answer ! The reason I did not use the chemistry options in Fluent is that I want to get a better understanding on defining source with UDF. Since numerical formulation for chemical reaction simulation is provided in detail in the help document (theory guide), I thought this is a good reference. What now I am wondering is: is it possible for simulating a fluid flow problem involving chemical reaction with Eulerian multiphase model + Source UDF?Is there any difference in the simulation results gained through 19.2 and 2023 version? The chemical reaction in my problem is a decomposition reaction (A (liquid)= B(gas) + C(liquid)). "the chemical and phase part(eg latent heat)" what is the chemical part?
