What is it about?
Plasma synthetic jet actuators are tiny, fast-acting devices that can push air without moving parts by using short bursts of electrical energy. In this study, we tested a group of these actuators arranged side by side—called an array—and observed how they produce powerful bursts of air and shock waves immediately after firing. Using ultra-fast imaging, we found that each actuator first sends out a series of rapid blast waves, which then interact to form a focused “jet-like” flow even before the main air jet appears. This behavior could help control airflow over aircraft wings or in engines, especially at high speeds. Our work shows that arranging these actuators in arrays expands their influence compared to a single unit, making them more practical for real-world applications.
