摘要:

利用合成射流对细长旋成体大攻角非对称涡控制进行了研究,基于合成射流激励器设计了一频率高达1 kHz的非定常小扰动控制机构,并将其成功应用于大攻角非对称涡主动流动控制。应用天平测力和七孔探针流场测试技术,研究了合成射流非定常小扰动电压和频率对非对称涡的控制特性和规律。结果表明,采用合成射流能够完全消除背涡的非对称性,扰动频率是影响非对称涡控制的一个关键参数,高频扰动下模型背风区非对称涡结构趋于无控制流态。且文中结果发现,当攻角α=57.5°、非定常小扰动频率fs=150 Hz时,即可将非对称涡完全控制成为对称涡。

Abstract:

The research of high angle of attack asymmetric vortex control for slender body has been conducted by using synthetic jet, a frequency up to 1 kHz unsteady small perturbation control devices based on synthetic jet actuator is designed, which has been successfully applied to asymmetric vortex active flow control at high angle of attack. With techniques of balance force and seven holes probe flow field measurements, the characteristics of asymmetric vortex control by the synthetic jet unsteady small perturbation voltage and frequency are explored. The results show that the synthetic jet can completely control the asymmetry vortex, frequency is the key parameter that would affect asymmetric vortex control and high frequency perturbation asymmetric vortex structure tends to be the uncontrolled flow pattern. And it is found that when angle of attack α is 57.5° and unsteady small perturbation frequency fs is 150 Hz, the complete control of the asymmetric vortex can be realized, converting into symmetric vortex pattern.

Key words: asymmetric vortex control, synthetic jet, active flow control, high angle of attack, unsteady perturbation, seven holes probe
