Abstract: The anti-icing performances of streamwise and spanwise plasma jet actuators fixed on NACA0012 are compared in the icing wind tunnel. Streamwise and spanwise actuators are designed and installed on the model surface, and thermocouples are specially embedded beneath the actuator to detect the anti-icing effects. Experiment results indicate that the spanwisely installed actuator cannot generate plasma jets due to the installation position being above the exposed electrode, leading to icing and thus a poor performance of anti-icing, while the streamwisely installed actuator realizes anti-icing by contrast.
