I am trying a reaction in fluent for which i have its rate equation. i have written a udf and the udf is compiling and is hooked in fluent. but when i open the reactions panel for finite rate it asks the preexponential and activation energy. can someone help me by giving the procedure of using the rate equation to run the reaction in fluent. |

you have to give pre-exponential factor and activation energy in Fluent Reaction panel. Fluent will pass these values to your UDF.

thanks for ur reply. but I have a reaction rate equation where the k value and keq value are expressed in terms of temperature. so the udf will take the temperature from the fluent and calculates the rate of the reaction. I want to use this reaction rate instead of the rate expressed by arrhenius type in the reactions panel. how to do that |
