...-dimensional, isothermal model. The heterogeneous surface chemistry is modeled by considering standard and fast SCR mechanisms, and the mass transfer rate is described by using a one-dimensional film model and dimensionless Sherwood (Sh) number. The paper investigates the effect of Sh numbers on the catalyst...

... a temperature difference. Because of the different heats of formation and sensible enthalpies associated with the chemical species, this assumption is reviewed and a conclusion as to the model formulation is presented. diesel engines exhaust systems filtration pollution control surface chemistry...
