摘　　要：对雾化气体压力及导流管伸长量对导流管顶端气体流场的影响进行了研究.结果表明:随着雾化气体压力增加,导流管顶端压力先降低后升高;气体流场发生开涡-闭涡转变时雾化气体压力升高、导流管顶端压力降低;闭涡状态下,导流管顶端压力与雾化气体压力成直线关系,且随着导流管伸长量增加,直线斜率减小.This article studies the effect of atomization gas pressure and delivery tube protrusion length on delivery tube tap filed.The results shows that：with atomization gas pressure increase,the delivery tube tap pressure first decrease then increase;as gas filed changes from open-wake to closed-wake,the atomization gas pressure increase and delivery tap pressure decrease;in closed-wake state,the delivery tap pressure has a line relationship with the atomization gas pressure,and with the protrusion length increase,the straight slope decrease.
