Energy Conversion in Effervescent Atomization
Original language description
Atomization of liquids is, from energy point of view, a process of transformation of an input fluid energy in-to surface energy of produced droplets. We qualitatively describe processes during internal flow, discharge of two-phase mixture as well as spray formation with particular focus to the energy transfer in effervescent atomi-zation. Near nozzle spray visualization elucidates the liquid breakup at different operation modes. General ener-gy equation for steady homogeneous flow is used to explain theenergy forms involved in the atomization pro-cess. Numerical results illustrate their values and an influence of operational conditions on relations between different energy forms. Main part of the paper is focused on the atomization efficiency. Simplemethod for esti-mation of the atomization efficiency of pneumatic atomizers is proposed; surface energy of created droplets, estimated using PDA data, is compared with energy required for the atomization.
