Summary:Title screen
In this paper, we describe the results of experimental research into secondary droplet atomization for several heterogeneous, water-oily liquid compositions including some highly heterogeneous emulsions and slurries. The group of schemes is studied, in addition to relevant experiments reported in the literature: droplets colliding with each other, with a heated or not heated walls, and with an air flow, as well as exposed to conductive or convective heating followed by micro-explosive breakup. After the analysis of experimental data, we calculate the size and number distributions of the liquid fragments generated using each of the approaches. We determine the duration of initial droplets' fragmentation as a function of the We numbers and the density of the supplied heat flux. The comparative analysis gave us optimal conditions for several aerosol generation techniques providing minimal fragment size with relatively low electric power consumption. It is shown that each of used atomization techniques provides a comparable number of liquid fragments on average, considering the amount of power required. Several techniques for combined atomization are proposed, based on the investigated approaches.
