Considerable difficulties attach to the mathematical description of the motion of a system of spherical bubbles of identical dimensions in a liquid, at large Reynolds numbers. At present, there are several known approaches to the solution of the problem, based on the application of the cell model [1–4]. For small Reynolds numbers, a more rigorous description of a system of spherical bubbles was attempted in  by means of the Tam method , using the approximation of “point∝ forces with successive averaging over ensembles. In the present paper, the Tam method is used to describe the motion of a system of spherical bubbles of identical size at large Reynolds numbers. The drag force exerted by the liquid on a specimen bubble of the considered system is calculated.
