摘要
针对锥形碰撞壁对自激振荡压力波的影响,建立了涡旋与锥形碰撞壁相互作用的不可压缩二维涡线数学模型。讨论了锥形碰撞壁的保角变换,并对变换平面λ中点涡的复速度势进行计算;分析研究了锥形碰撞壁对自激振荡压力的影响。
The mathematical model of incompressible two-dimension liner of vortex for interaction of the discrete vortex with the taper impinging edge is established against the effect of the shape of impinging edge on the self-excited oscillation. The conformal mapping of taper impinging edge is discussed and complex velocity potential for point vortex in the conversion λ plane is calculated. The effect of taper impinging edge on the self-excited oscillation pressure is analyzed.
