| Outline of Final Research Achievements |
A study was conducted to characterize and model the electrohydrodynamic force and heating fields generated by a plasma actuator. By upgrading the simulation model of plasma and coupling it with air flow, we succeeded in reproducing the experimental results with an accuracy of about 10%. The influence of the electrohydrodynamic force and the heating on the flow was also discussed by considering the results of the BOS method, the flow field by the PIV method, and the surface temperature measurement by an IR camera. Finally, we developed a method to estimate the electrohydrodynamic force field as a Gaussian distribution by assimilating the measured velocity and density fields into a numerical simulation.
