摘　　要：对纺粘牵伸器拉伸气流流场进行了数值模拟,分析了高压气流射流流场内速度、压力以及湍流动能的空间分布情况,并根据模拟结果,结合实际生产工艺条件,对出口端的压力值进行实地测量,验证了模拟的准确性。The drawing flow field on spunbond process was tested with method of figure imitation, the distribution of velocity and pressure as well as turbulent kinetic energy in the field of air jet flow with high pressure were analyzed. Base on the imitation result, the pressure in the exit was measured actually combining with practical production technique and the accuracy of imitation test was confirmed.

关 键 词：纺粘牵伸器 气流流场 数值模拟 湍流动能
