Conventional wire drying typically relied on high-speed air-jet blowing， which had issues such as extremely thin liquid films on the wire surfaces and a small area affected by the airflow. Applying ultrasonic energy directly to the wire structures so that the solid-liquid interface underwent high-frequency vibration and an ultrasonic atomization effect was produced. An energy-consumption model coupling ultrasonic atomization and high-speed air jets was developed， and comparative experiments were carried out focusing on key parameters such as ultrasonic power and droplet volume. Results show that ultrasound induces rapid droplet spreading and atomization via capillary waves and acoustic cavitation， and the liquid-film removal efficiency is markedly superior to that of air jets. At a droplet volume of 10 and an exposure time of 18 ms， 360 W ultrasound achieves a removal rate of 84.37%， whereas a 450 W high-speed air jet removed only 8.58% of the film. In terms of energy consumption， under conditions producing equivalent removal， ultrasound reduces system energy use by at least approximately 46.7% compared with air jets. This paper demonstrates the feasibility of ultrasonic-assisted rapid， energy-efficient dewatering and drying of wire surfaces.
