The application of the ultrasonic atomization has been extended because of its good merits. Influx, liquid load, and physical properties are the effecting factors to the size of spray droplets. In this study, distilled water and city water are selected as reference liquids and gasoline, kerosene, and petroleum as fuel liquids. Characteristics and affinity to get the maximum effect for the ultrasonic atomization are observed by using the two ultrasonic transducers with 28KHz and 2MHz.<br/> Results show that the size distributions of liquid spray droplet by direct vibration method prevail over the aerosol method in uniform droplet size and as a whole, liquid droplet sizes and spray quantum are decreasing according to the head increasing.<br/>

A Study on size distributions of the liquid atomization by ultrasonic was carried out using 3 methods, such as direct vibration, aerosol and improvement method. Distilled water and city water were selected as the reference liquids and gasoline, kerosene and petroleum as fuel liquids. Two kinds of ultrasonic transducers, with 28kHz and 2MHz were used. Characteristics and phenomena on ultrasonic atomization were observed and examined relatively according to influx and liquid load by using the Malvern system. In results, The best uniformity of particle size was achieved by the direct vibration method, and their mean size was 10 times larger than that of the aerosol method.
