Nanosecond pulse plasma activation of micron‐sized mist droplets
Plasma‐activated mist (PAM) has seen increasingly widespread applications in areas such as surface disinfection and fog cultivation. The high‐resolution time diagnostics of ns pulse plasma interacting with micron‐sized droplets under high‐humidity conditions is challenging to achieve with existing experimental methods. This paper employs a global model to study the interaction between plasma and droplets, offering a detailed analysis of the plasma's transition from the gas phase to the liquid phase. It was discovered that in high‐humidity environments, hydrated ions become the predominant ion species. These acidic active substances in PAM droplets are the primary factors in the mist's ability to kill bacteria. The paper further examines how variations in droplet size and discharge voltage influence the PAM's activity.
