摘要:

利用等离子体合成射流激励器,采用风洞试验和数值仿真的方法,对钝头体在高速复杂流场中的减阻特性进行研究。在马赫数为8的高速流场中,开展了等离子体合成射流作用下的钝头体阻力动态测量试验,探究了等离子体合成射流不同穿透模态对钝头体阻力的影响,建立了适用于等离子体主动激励与高速流动耦合作用下的数值仿真方法。风洞试验结果表明,等离子体合成射流使钝头体模型减阻2.51 N;数值仿真结果表明,等离子体合成射流使钝头体模型减阻2.03 N,相对试验值减阻误差为19.1%。

Abstract:

The influence of the plasma synthetic jet on the drag reduction characteristics of the blunt body model in high-speed complex flow fields is investigated experimentally and numerically. The dynamic axial force measurement test of the blunt body with a plasma synthetic jet actuator is carried out in Mach number 8 flow field. The mechanism of penetration model on drag reduction of the blunt body by the plasma synthetic jet is studied. A numerical simulation method suitable for the coupling of plasma active actuation and high-speed flow is established. The wind tunnel test results show that the plasma synthetic jet reduces the drag of the blunt body model by 2.51 N. The numerical simulation results show that the plasma synthetic jet reduces the drag of the blunt body model by 2.03 N, and the relative experimental error of drag reduction is 19.1%.

Key words: high-speed flow, plasma, flow control, drag reduction, wind tunnel test
