We calculate the effective reaction rate constant k∗ and the effective diffusion constant D∗ for a system of independently distributed overlapping sinks as functions of the volume fraction φ of the sinks and the Sherwood number Sh. The Sherwood number characterises the strength of the...

We calculate the effective reaction rate constant k∗ and the effective diffusion constant D∗ for a system of randomly distributed imperfect spherical sinks. Imperfect means in this context that the surface reaction rate is finite. We use an effective medium theory presented in a previous...

We calculate the effective rate constant k∗ and the effective diffusion constant D∗ of diffusion-controlled reactions in a random array of perfectly absorbing spherical sinks. We use the effective medium approach developed by Cukier, Freed and Muthukumar. In contrast to their work we take...
