Eulerian multiphase model for species trnasport: UDF for reaction rate
 
Hii

I have been trying to solve the tutorial:Using the Eulerian Multiphase Model with Species Transport for Ozone decomposition. In the tutorial they have used an UDF for defining reaction rate. Is this UDF available elsewhere or anyone can please mail. I dont have access to fluentusers.com. It will be of great help as I am running out of time.

Thanks in advance

hi harsh,
i m also searching for UDF for reaction rate in heterogeneous reaction in biomass gasification. if i will get i will send to you.. if you will get send me too (my mail id : prishor@gmail.com). pls give me your mail id,
meantime you can try to make the UDF for the same. tutorial for UDF are available online.. i am going through it. but its very hard to make in a short time. anyway keep searching..i m also searching it as i require it at the earliest..
thanks and regards,
prishor
