In this work, a two-phase hydrodynamic model is proposed to describe flows occurring in a thin layer of emulsion containing active Brownian particles (drops). The peculiarities of the two-dimensional flows formed in the emulsion are demonstrated. It is shown that during the collective motion of active droplets, the kinetic energy is distributed over spatial scales according to patterns typical of developed turbulent flows, including the transfer of energy to large scales and the formation of large-scale vortex structures. The kinetic energy transferred from droplets to the liquid phase is concentrated in short-wavelength disturbances that determine the mechanism of changing the direction of droplet motion in addition to their diffusive rotation and turning due to repulsion when colliding with other droplets.
