✦ Synopsis

The flow of a fluid, containing a reactant, past a solid catalytic particle on which a reaction takes place is considered for large P6clet number. The concentration of the reactant is given by the diffusion boundarylayer equation, and this is solved in the case when the rate of reaction on the particle surface and the rate of diffusion of reactant onto the surface are of the same order of magnitude.

For a spherical particle, a series solution for the concentration is found for the case of Stokes flow, and numerical solutions are found for Stokes flow and for flow at higher Reynolds numbers (up to Re = 10). To examine the effect of particle shape, numerical solutions are found for prolate and oblate spheroids in Stokes flow.
