Numerical Simulations of NS-DBD Plasma Actuators For Flow Control

Nanosecond dielectric barrier discharge (NS-DBD) plasma actuators is relatively<br/>new means of flow control. It has several advantages compared to more conventional<br/>means of flow control, such as small size, low weight, fast response time<br/>and controllability. It has been demonstrated to be able to promote transition of<br/>boundary...

Experimental method to quantify the efficiency of the first two operational stages of nanosecond dielectric barrier discharge plasma actuators

A method to quantify the efficiency of the first two operational stages of a nanosecond dielectric barrier discharge (ns-DBD) plasma actuator is proposed. The method is based on the independent measurements of the energy of electrical pulses and the useful part of the energy which heats up the gas in the discharge region. Energy input is...

Method to quantify the electrical efficiency of a ns-DBD plasma actuator

An experimental investigation was conducted on the effective efficiency of a nanosecond Dielectric Barrier Discharge (ns-DBD) plasma actuator. Back-current shunt technique and infrared thermography measurements were carried out at the same time on an upside-down flat plate in a quiescent environment. The only investigated parameter was thickness...
