Eng.) - Asian Institute of Technology, 2020  aPlasma actuators has been a new technology used for the flow control in the field of  aerodynamics. However, the research has not been carried out in the field of structural  engineering. So, Plasma actuator has been applied with the view of control for civil engineering  structures. So, the project is the blend of the electrical and structural engineering. Initially, plasma actuator driver circuit is prepared meeting the requirements of high  voltage and high frequency. The output from the driver is applied to a dielectric barrier  discharge actuator prepared with copper electrodes in either side of the dielectric barrier. Due  to the ionization of air plasma is generated along with electric wind (due to the electric wind).  Electric wind is a significant major parameter to for the flow control. So, the actuators are  optimized to attain the maximum possible electric wind for the aerodynamic response control. These actuators are applied to the basic bluff body shapes, square and circle at different  strategic locations. These models are tested in the wind tunnels at different wind speeds. High  Frequency Pressure Integration test is carried out in the wind tunnel. The mean and the  fluctuating components of the aerodynamic forces is analyzed. The effect of plasma actuation  is definitive from the analysis. Smoke test is also carried out to provide further qualitative  evidence to the effectiveness of plasma actuation. 0aActuators 0aWind-pressure 0aStructural dynamics0 aPennung Warnitchai,eChairperson1 aAnwar, Naveed,eExamination Committee0 aPunchet Thammarak,eExamination Committee0 aSuvit Punnachaiya,eExamination Committee0 aPhongphaeth Pengvanich,eExamination Committee2 aAsian Institute of Technology Fellowship,eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
