초록

Chronic wounds necessitate periodic treatment and management due to their potential for serious complications. Recently,ultrasonic mist therapy has been introduced to treat chronic wounds efficiently. This therapy requires a noncontact sprayingmethod to prevent side effects such as bacterial infections and pain. Therefore, research is needed on a spray nozzle tip thatcan effectively transmit ultrasonic energy to the wound target with misted cleaning solution mobility in a specific direction andat an appropriate speed. The performance of the nozzle tip is greatly affected by the flow characteristics inside it.
Computational fluid dynamics (CFD) is a powerful tool to analyze these characteristics in detail. The behavior of the mist wasanalyzed in a simulation based on discrete phase model methodology in an unsteady state. Valid design parameters enablingnoncontact cleaning were determined by setting the design parameters of the nozzle tip`s internal flow path and measuring thespraying speed of the mist using CFD analysis. Through the simulation results, information on the sprayed skin surface andspray characteristics are measured. Lastly, we present a nozzle tip design guide optimized for ultrasonic mist therapy.
