WebA Damkohler number (Da) is useful ratio for determining whether diffusion rates or reaction rates are more ‘important’ for defining the steady-state solution over the length and time scalesof interest. Hence the definition: (1) Da is associated with characteristic diffusion and reaction times therefore scaling is necessary.
WebNov 2, 2024 · The reaction kinetic rate and mass transport play an important role in the sizing and scale-up of reactors.
