【摘要】 本文提出了一种利用两支单点压力传感器对实验室有限长柱体的模拟流动进行动态测量的实验方法。通过压力过程曲线的空间转换,去除了由于采用有限长柱体而带来的端部效应,较为准确地获得了液环柱塞流动的压力梯度值。更多还原

【Abstract】 The dynamic measurement in laboratory was taken for limited column simulating flow by using two transmitters with single point pressure. Through the space transform of pressure process curve, the end effect caused by use of limited column was elminated, the pressure gradient in liquid annulus flow was obtained correctly.更多还原
