The initial instability development has been investigated for different modes of artificial disturbances and oncoming wind speeds . experimental studies in natural conditions are performed , where only artificial primary unsteady and steady disturbances are introduced 在人工施加非定常基頻與定常擾動的自然條件下,對橫流控制的高頻二次不穩(wěn)定性進(jìn)行實驗研究。
