The arc plasma enhanced groove turbulence friction resistance reduction device comprises a groove wall face (1) and arc electrode sets (2), the groove wall face (1) is formed by a plurality of grooves which extend in the flow direction and are distributed at equal intervals in the spanwise direction, and the arc electrode sets (2) are arranged on the groove wall face (1) in an array mode. The invention further provides a corresponding drag reduction method. The method comprises the steps that the sensors are arranged in flow field data collected by a flow field, and the data are input into the controller; the controller analyzes the data and selects a working mode and parameters according to the data; the sensor collects flow field data again, and flow field information after arc discharge is collected; and the controller analyzes the data again, measures the surface friction resistance and compares friction resistance changes before and after arc discharge, if the expected resistance reduction effect is achieved, the work is finished, and otherwise, the second step is repeated to select a new working mode or discharge state. The active control arc plasma discharge is combined with the groove passive flow control technology, and effective drag reduction can be achieved under the actual flight complex incoming flow condition.

    提供一种电弧等离子体增强型沟槽湍流摩擦减阻装置,包括沟槽壁面(1)和电弧电极组(2),沟槽壁面(1)由多个沿流向延伸并沿展向等距分布的沟槽形成,将电弧电极组(2)以阵列的形式布置于沟槽壁面(1)上。还提供相应减阻方法:将传感器布置在流场采集流场数据中,并将数据输入到控制器中;控制器对数据进行分析,据此选择工作模式和参数;传感器再次采集流场数据,收集电弧放电后的流场信息;控制器再次对数据进行分析,测量表面摩擦阻力,对比电弧放电前后摩擦阻力变化,若实现预期减阻效果,工作结束,否则重回第二步选择新的工作模式或放电状态。本发明采用能够主动控制的电弧等离子体放电与沟槽被动流动控制技术相结合,能够在实际飞行复杂来流条件下实现有效减阻。
