用PIV测量介质阻挡放电(DBD)等离子体制动器来计算体积力

Plasma actuators have been identified as having great
promise for flow control applications. A single dielectric
barrier discharge (SDBD) plasma actuator consists of two
staggered electrodes separated by a dielectric layer (Fig.
1). When an AC voltage of sufficient amplitude (a few kV)
is supplied to the exposed electrode, it causes the air over
the covered electrode to weakly ionize, resulting in a cold
plasma. An electro-mechanical coup领 with the ambient
air is provided by the interaction between the ionized air
and the electric field between the two electrodes, generating
a body force. 德国LaVision PIV/PLIF粒子成像测速场仪 Imager LX PIV相机 用于粒子成像测速(PIV)的荧光示踪粒子
