【摘要】：为了监测天然气水合物生成及分解过程中物性参数的变化规律,需要在反应釜中安装各种传感器测点,而测点的引入会对反应釜中的流体流动产生影响。为了有效减少测点对反应釜产生的干扰,利用数值模拟方法对测点尺寸与测点最小间距之间的关系进行了定量研究。结果表明,传感器测点的引入会对反应釜中的渗流场产生影响,测点尺寸越大、测点的间距越小,对渗流场的影响越大;对于尺寸为10 mm、9 mm、8 mm、7 mm和6 mm的测点,相应测点最小间距分别为60 mm、54 mm、48 mm、42 mm和36 mm时测点对反应釜流场的影响可以忽略不计。因此对反应釜进行传感器测点排布时,测点的间距不得小于测点尺寸的6倍,研究结果对同类实验反应釜中测点的合理布置具有重要参考价值。
[Abstract]:In order to monitor the variation of physical parameters in the process of gas hydrate formation and decomposition, it is necessary to install various sensor measuring points in the reactor, and the introduction of the measuring points will have an effect on the fluid flow in the reactor. In order to effectively reduce the interference of measuring points to the reactor, the relationship between the measurement point size and the minimum distance between the measured points was studied quantitatively by numerical simulation method. The results show that the introduction of sensor points will have an effect on the seepage field in the reactor. The larger the measuring point size, the smaller the distance between the measured points and the greater the influence on the seepage field, and for the measuring points with the dimensions of 10 mm / 9 mm / 8 mm / 7 mm and 6 mm, The effect of the measuring points on the flow field of the reactor can be neglected when the minimum spacing of the corresponding measuring points is 60 mm / 54 mm / 48 mm / 42 mm and 36 mm respectively. Therefore, the spacing of the measuring points should not be less than 6 times of the size of the measuring points in the arrangement of the sensor measuring points for the reactor. The results of the study have important reference value for the reasonable arrangement of the measuring points in the same type of experimental reactors.
