Краткое описание

An experimental study has been conducted to analyze the characteristics of ultrasonic atomization when working with some alkanes and alcohols. Ultrasonic atomization is very convenient because it can generate droplets with diameters of a few microns, with very narrow size distribution, and at low velocity. To date, most of the published results have been limited to experiments with water. However, it has been demonstrated that atomization rates quickly decrease as liquid viscosity increases. To produce droplets of high viscosity liquids, first they can be diluted in volatile solvents with low viscosity, and then the mixture can be atomized afterward. To facilitate this possibility and advance the understanding of the dependence on different physical properties, this work analyzes the characteristics of ultrasonic atomization of some organic compounds commonly used as solvents. In particular, hexane, heptane, decane, methanol, ethanol, and 2-propanol were considered. A commercial piezoceramic disk with a resonance frequency of 1.65 MHz was used in the experiments, and the atomization rates were measured. The sprays were characterized by analyzing instantaneous images and high-speed video sequences and measuring droplet size distribution functions. The results confirm that the viscosity strongly conditions the atomization efficiency. The role of other fluid properties is more difficult to ascertain, but some experiments were performed to elucidate it.
