Abstract (English):
We study the mixing process in the apparatus for the preparation of aqueous mixtures forming fire-extinguishing foam. The focus is on the relationship between the intensity of mass transfer and turbulent diffusion koffitsenta a rate of energy dissipation. It is shown that the intensity of mixing at high energy dissipation (100 W/kg) depends on the irregularity of its distribution in terms of the device, which can be taken into account by introducing the fractal dimension of the field dissipation.
