BOUNDARY LAYER CONTROL VIA NANOSECOND DIELECTRIC/RESISTIVE BARRIER DISCHARGE

摘要

A System for controlling boundary layer of a fluid flowing over the surface of a body (2) is described. The system comprises at least one nanosecond- dielectric/resistive barrier discharge plasma actuator (1) disposed on said surface of said body (2) at a specific location according to the task to be performed, at least one probe (8), placed on the surface of said body (2) at a specific location according to the task to be performed by said actuator (1), to measure characteristics of the flow and to emit signals corresponding to said characteristics, a highvoltage nanosecond pulse generator (6) to apply at least one specific high voltage nanosecond pulse to said at least one actuator (1) and a controller (9) connected to said probe (8) to drive said highvoltage nanosecond pulse generator (6) according to said signals emitted by said probe (8). Different application scenario of the system are described.
