hello,

I'm new and fluent ansys: I implemented the following reaction cracking using arnhenius model:

EDC -> VCM + HCl


My doubt was how to implement a UDF to fnte of enegia term that is given by:

source = ra (reaction rate) x enthalpy (const).

ra = k * Exp (-and / RT)

T - Temperature.
K, EA - Constant.

the model in a reactor, a tube 2D model, makes the heating rate varies along the reactor function of (x).

The reaction law implemented in fluent!

thanks
