| Abstract: | The problem of steady-state convective diffusion to a solid spherical particle located in a Stokes flow was discussed in 1] in the approximation of a diffusion boundary layer. The region of the rear critical point at which the boundarylayer solution is inacceptable was investigated in 2, 3]. With the investigation of the diffusional interaction of several particles in a stream of liquid (for example, two spheres with a common axis, directed along the flow), we must know the distribution of the concentration in a region of small angles behind the body, giving the flow for the following particle. In the present work a solution is given to the problem of the distribution of the concentration in the diffusional wake of a spherical particle. It is shown that the concentration rises proportionally to the square root of the distance to its surface.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 176–179, January–February, 1977.The author thanks Yu.
