A parametric study was conducted to explore the thermal characteristics of ns-DBD plasma actuation in different environmental and flight conditions, and evaluate the potential of leveraging ns-DBD plasma actuators for aircraft in-flight icing mitigation. The parametric study was conducted in the unique Icing Research Tunnel available at Iowa State University (i.e., ISU-IRT). While the transient thermal characteristics of ns-DBD plasma actuation over a NACA0012 airfoil/wing model under various test conditions were revealed by using an infrared (IR) thermal imaging system, the anti-icing performances of the ns-DBD plasma actuators under different operational and environmental conditions were also evaluated and compared by using a high-speed imaging system together with the synchronized thermal imaging of the ice accreting surfaces. The impact of incoming airflow velocity, airflow temperature, and AOA of the airfoil/wing model on the thermal characteristics of ns-DBD plasma actuation as well as the anti-icing performances of the ns-DBD plasma actuators at different ns-pulse frequencies and airflow temperatures were systematically investigated, which provided a guideline for the further optimization of ns-DBD plasma actuators tailored specifically for aircraft icing mitigation. It was found that the dynamic heating process of the airfoil/wing surface induced by the ns-DBD plasma actuation is strongly dependent on the environmental parameters, such as the incoming airflow velocity, air temperature, and the AOA of the airfoil/wing model. The findings derived from this study provided a guideline for the further optimization of ns-DBD plasma actuators tailored specifically for aircraft icing mitigation to ensure a much safer and more efficient aircraft operation in atmospheric icing conditions.
