WAVE CHARACTERISTICS OF LIQUID JETS FROM AIRBLAST COAXIAL ATOMIZERS
ABSTRACT
Results of wavelength and frequency measurements are presented for liquid jets issuing from airblast coaxial atomizers. The liquid jet surface wavelengths were measured from the photographs for liquid jet velocity ranges of 1.1−18.2 m/s and air velocity ranges of 45.8−130 m/s. Frequencies were measured using a laser beam attenuation technique. The results show that wavelengths decrease with the liquid and gas jet velocities. The frequency band of the jet surface oscillations increased with the liquid jet velocity. Average frequencies were found to increase with both the liquid and the gas jet velocities. The resulting wave propagation velocities were insensitive to the variation of these velocities.
