摘要
文中采用实验研究和理论分析两种方法对微含气液体管道压力波波速的特性进行了研究。设计了实验装置及数据采集系统,测量不同含气率下和管道不同位置的压力波波速,编制程序对采集的数据进行处理分析。引入压力波大小对波速的影响,对波速公式进行修正。分析了气液混合物的流动状态对波速的影响。结果表明:修正后的公式拟合值与实验结果基本吻合;气体在液体中的弥散程度越均匀,压力波波速越小,反之则越大。
Two methods of the experimental study and theoretical analysis were taken to study on pressure wave velocity characteristics in liquid with trace amount of gas pipeline. The experimental equipment and data acquisition system were designed,and the velocity of pressure wave in different gas rate and different position in pipeline were measured,then program was done to process and analysis the data. The effect of pressure wave size on wave velocity was taken into consideration,and the existing wave velocity formula was modified. The effect of flow pattern of gas-liquid mixture on the wave velocity was analyzed. The result shows that modified formula and test value are mainly consistent. And the more the dispersion degree of gas in liquid is,the smaller the pressure wave velocity is,and vice versa.
