Abstract

Now investigators of different countries devoted a considerable attention to studying the physical processes in suspension flows, especially to the energy exchange between solid and fluid phases of these flows, what determines to a large extent the life time of solid particles in every flow. The last circumstance in its turn influences the optical properties of the environment, for example, by decreasing the limpidity of a liquid, when concentration of solid particles increases, and vice versa. Of course, it is necessary to take into account not only the concentration, but also the particle size distribution (the spectrum of particles) . Besides, the settling velocity of particles is one of the parameters which determine the ecological status of different water objects. It is known, that solid particles are carried by water flows, may absorb chemical and radioactive poilutants, transport them on big distances.
