Investigation of the Effect of DBD Plasma Actuator Excitation Frequency on Flow Control Around an Aircraft Wing
Abstract
In this study, the effect of variation of plasma excitation frequency and applied voltage
variation on lift coefficient of NACA0015 airfoil is investigated at Re=48 000. In this context, the effects of
the parameters direct effecting the plasma generation on the aerodynamic performance of the airfoil are
assessed. In this study, plasma actuators are located at near leading edge (x/C=0.1) position. Within the
scope of the experimental studies, the separated flow is studied for the excitation frequency at high
attack angles. When the studies in the literature are taken into consideration, it is seen that the majority
of the studies are performed for stall angle and post stall angles. In experimental studies, the effects of
frequency and voltage are examined for a certain angle of attack angle. As a result of the experimental
studies, the direct proportional effect of the application voltage of the plasma actuators on the lift
coefficient was determined. On the other hand, no significant correlation was found between excitation
frequency. This relationship appears to be more of a non-linear structure. This has been examined in
detail in the findings section of the study.

DBD PLAZMA AKTÜATÖR SÜRÜM FREKANSININ UÇAK KANADI ETRAFINDAKİ AKIŞIN KONTROLÜNE ETKİSİNİN İNCELENMESİ
Abstract
Yapılan çalışma ile NACA0015 uçak kanadı etrafındaki akışın kontrolünde plazma aktuatörlerin
Re=48 000 değerinde sürüm frekansı ve voltajındaki değişmenin kaldırma kuvvetine etkisi incelenmiştir.
Bu kapsamda yapılan çalışmalar ile plazmanın oluşturulmasında etkili olan parametrelerin direkt olarak
aerodinamik performansa etkisi değerlendirilmiştir. Yapılan incelemede plazma aktüatörler uçak
kanadının ön kısmına (x/C=0.1) yerleştirilmiştir. Deneysel çalışmalar kapsamında ise frekans değişimi ile
yüksek hücum açılarındaki ayrılan akışın incelemesi yapılmıştır. Literatürdeki çalışmalar göz önüne
alındığında çalışmaların büyük çoğunluğunun stol açısı ve post stol açıları için yapıldığı görülmektedir.
Yapılan deneysel çalışmalarda, belirli bir hücum açısı aralığı için frekansın ve voltajın etkileri
incelenmektedir. Yapılan deneysel çalışmalar sonucunda elde edilen bulgulardan özellikle plazma
aktüatörlerin uygulama voltajının kaldırma katsayısına doğrudan oransal etkisi tespit edilmiştir. Diğer
taraftan, sürüm frekansının ise belirgin bir ilişkisi tespit edilememiştir. Bu ilişki daha çok doğrusal
olmayan bir yapı şeklinde görünmektedir. Bu durum, özellikle çalışmanın bulgular kısmında detaylı
olarak incelenmiştir.
