Effects of Acoustic Modulation and Mixed Fuel on Flame Synthesis of Carbon Nanomaterials in an Atmospheric Environment.

In this study, methane-ethylene jet diffusion flames modulated by acoustic excitation in an atmospheric environment were used to investigate the effects of acoustic excitation frequency and mixed fuel on nanomaterial formation. Acoustic output power was maintained at a constant value of 10 W, while the acoustic excitation frequency was varied ( = 0-90 Hz). The results show that the flame could not be stabilized on the port when the ethylene volume concentration (Ω) was less than 40% at = 10 Hz, or when Ω = 0% (i.
