Combusting particle – Fluent

    • jacobian

      Hello everyone. 

      I have some doubt about the implementation of latent heat of evolving volatiles in a combusting particle in ANSYS Fluent 2023 R2. From the manual, you can see that:

      And for a combusting particle it says that it is the heat required for the evolution of volatiles - Eq. 12-139. which is below:

      But actually, there is no latent heat included in this particular equation. I am asking, because in the same energy equation for particle evaporation, latent heat is included in that equation. So for a combusting particle, is this latent heat a heat of pyrolysis?


      Let me know what you think

      Hi Jacobian,


      The left side term in the heat transfer equation i.e heat transfer due to change in enthalpy will take care of the latent heat term.
