Abstract

Liquid atomizing modes ensuring compliance with the specified operating modes of a model aviation engine by the basic similarity criteria were modeled. Functional dependence of Sauter mean diameter of the fuel drops on the tests mode based on energy approach was revealed. Tests of atomizing unit on the laser measurements test bench were accomplished. The PSV (Passive Shadow Velocimer) laser-optical method as well as stray light fluorescence method were employed for nozzle spray characteristics obtaining. Computational result demonstrate good correlation with the experimental data for the studied modes of kerosene spraying by the pneumatic atomizer.

Keywords:

liquid atomization, pneumatic atomizer, engine operating mode, similarity criterion
