摘要:
An oscillating piezoelectric beam was used on the prefilming surface in a two-dimensional model of the prefilming-type aircraft fuel atomizer to interact with the periodic phenomena occurring inside the nozzle and just at the atomizing exit-edge of the prefilming surface. The oscillating beam was designed such thatits second mode of oscillation resonated at frequencies close to the above-mentioned periodic phenomena.It was shown that the spray Sauter Mean Diameter (SMD) and mean drop velocity profiles became more uniform at a distance of 50 mm from the nozzle for the condition tested. Cross-sectional-averaged SMD decreased slightly as a result of this novel feature.
