Default Help, UDF and define the surface reaction
Posts: n/a
CO and O2 flow through a pipe with diameter of 1mm, and the pipe is defined as a porous region. CO oxidation with O2 only takes place on the surface of the solid. Can anyone tell me how to define the surface reaction? The reaction rate is power law rate,namely, -r=A*exp(-Ea/R/T)*Cco^(-0.5)*Co2^1.2.The gas velocity is 0.17m/2.Thanks very much
