摘要
在固液两相流中,固体颗粒的浓度是随高度的变化而变化的,为表征这种变化,倪晋仁等提出了一个积分形式的浓度分布统一公式。该公式虽很有意义却并未有人给出解析解。通过使用变量代换和分解等数学手段,首先对统一公式进行求解,得出该公式的解析解,然后利用已有的实验数据和数值手段计算出公式中参数n的值,初步总结出影响n值的主要因素。
The concentration of solid matter in two - phase flow of liquid - solid gradually changes with the variety of height. In order to display this kind of change, professor Nijinren and other people gave an unified formula of concentration distribution. Though the formula is very useful, no one gives itb analyti- cal solution. By using mathematical methods like variable exchanging, variable decomposing, ere, the e- quation is solved and the analytic solution is first acquired, then the n value of parameter is obtained through the usage of numerical method and experiment data, then the influence of the main factors on n value can be initialy concluded.
