A steady state convective-diffusion equation is solved using a collocation method to find the concentration profile and flux of adsorbing particles near a particle adsorbed on the plane surface. At small values of the gravity number, NG=πd4Δρ/6kT, the concentration profile and flux vary slowly near the preadsorbed particle, while they are highly nonuniform at large values of NG. The effect of the position of the system boundary on the collocation calculation is discussed and it is shown how the concept of flux balance may be used to improve the accuracy of the results. Finally, we develop two fitting functions at high and low values of NG, respectively. © 1999 American Institute of Physics.
