Exergetic analysis of atomization process of liquid

The exergy balance equation for liquid atomization is discussed and exergetic efficiency of atomization is defined. On the basis of data taken from the literature some calculations of this efficiency have been carried out for the most widespread cases of atomization, i.e., for pressure and pneumatic atomization. The efficiency is low and does not exceed 1%. Some recommendations about how to carry out the full analysis of all items of the exergetic balance have been made. The results of such an analysis would give some indication of possible improvements in atomizer design and operating parameters.
