Euler-Euler heterogeneous reaction rate?
 

Hi users! I am trying to define the reaction rate of a heterogeneous reaction in an Euler-Euler approach with the UDF macro DEFINE_HET_RXN_RATE. The problem concerns solid particles which react with the surrounding gas. Which should be the units of the calculated r-r? Perhaps something like [Kgmol solids/m3 mixture - s]?

Thank you for your help!
