摘要

为了能有效地拓宽压气机的失稳裕度，在一台跨声轴流压气机上进行了基于介质阻挡放电（DBD）等离子体激励扩稳的实验研究.实验中分别选取了正弦交流电源和纳秒脉冲电源提供激励，并在跨声压气机40%设计转速和65%设计转速下对其扩稳效果和效率进行了对比分析.结果表明：在40%设计转速时，正弦交流电源和纳秒脉冲电源均能有效拓宽压气机流量范围，其中正弦交流电源激励方式能够使压气机综合失速裕度改善（SMI）达到15.33%.在65%设计转速时，两种激励方式的扩稳效果明显减弱，此时纳秒脉冲电源激励方式的扩稳效果更好.在压气机效率方面，纳秒脉冲电源对压气机设计点的效率影响更小，在40%设计转速时甚至能略微提升其设计点效率.实验结果表明，合理地选择激励方式有助于提高等离子体激励的扩稳效果，为实际压气机中基于介质阻挡放电等离子体激励扩稳措施的设计提供参考.

Abstract

In order to improve the stall margin

experiments were conducted in a transonic axial compressor with dielectric barrier discharge (DBD) plasma actuators. Power supplies of sinusoidal alternating current (AC) and nanosecond (NS) pulse were chosen to provide excitation. Improvement of the stall margin and efficiency of the compressor at 40% and 65% of its design speed were compared and analyzed. At 40% of design speed

AC and NS can extend the flow range of the compressor

and AC excitation got a stall margin improvement (SMI) of 15.33%. Effects of both actuations were significantly weakened at 65% of the design speed and the effects of NS excitation were better than AC excitation. In terms of efficiency

NS excitation had a smaller impact and even slightly improved the efficiency at 40% of the design speed. Experimental results show that appropriate choice of power supply can help to improve the effects of stall margin improvement and provide reference for the design of DBD plasma actuator in a real compressor.
