中文摘要:
      利用PIV系统,在静止空气中,定量测量了等离子体激励器的诱导速度场,分析了激励参数等因素对等离子体EHD顺电加速效应的影响。通过实验发现:在激励频率固定的情况下,诱导气流速度随着电压的升高逐渐增大;在激励电压固定的情况下,存在一个诱导气流速度最大的最优频率,并且不同的激励器对应不同的最优频率。另外,初步分析了激励器布局、绝缘材料以及通电时间对诱导气流速度的影响。
英文摘要:
      The induced velocity fields of plasma actuators were measured quantitatively in quiescent air by using Particle Image Velocimetry (PIV). In the meantime, that the analysis of excitation parameters and other factors' influence on plasma paraelectric EHD acceleration effect was also conducted. It is found that under fixed frequency, the induced airflow velocity increases as the applied voltage increases; while under fixed voltage, the induced airflow velocity has a maximum value under an optimal frequency, and actuator with different configuration has a different optimal frequency. In addition, other factors' influences on the induced airflow velocity were analyzed preliminarily, such as actuator configuration, insulated material and power time.
