If Damkohler number, NDa >>1, the reaction rate is much greater than the mass transfer rate and the overall reaction is controlled by the rate of mass transfer. In this case, the enzyme reaction can be described as (where Csb and Cs are the substrate concentration in bulk of solution and at the immobilized enzyme surface respectively. ks mass transfer coefficient, and a is the surface area of an immobilized enzyme particles)

    Damköhler’s numbers ( D a and D a I I ) are dimensionless numbers used to relate the intrinsic reaction rate to the mass transport rate [11]. D a is the ratio of the reaction rate to the global movement rate of the fluid (see supporting information S1).
