Performance characterization of plain-orifice injectors with very small holes

摘要

Results of an experimental of the flow characteristics and atomization quality of plain-orifice injectors fabricated by a new process are presented. The study includes an evaluation of the effects of length-to- diameter ratio, hole number, pressure differential, etc. on discharge coefficient, breakup length and drop size. Engineering correlations are derived for each of these parameters in terms of quantities such as Reynolds.
