ANSYS mixture material: Ethylene-oxygen
 

Dear all,

I want to define an ethylene-oxygen mixture (not ethylene-air) and I need some advice on the input parameters.

The one-step reaction is:

C2H4 + 3O2 = 2CO2 + 2H2O

What is the Pre-Exponential Factor, A and the Activation Energy (j/kgmol)? *Please take note of the units for the activation energy.

Also what should I define for the Mixing Rate?

The default inputs for ethylene-air mixture provided by Fluent is shown in the attachment for your reference. I have also attached a table with single-step reaction parameters (Units are cm-sec-mole-kcal-K).


Appreciate your replies!

Best,

Mnws
