可视化图象法评价滴流床液体分布 - The mainly objective includes two parts : one is to develop the mathematical m odel t o study t he flow m echanism o f 1 iquid i n t he b ed of tbr , and the other is to study the technology and device to distribute the liquid uniformly . in the first part , some theoretical models were established to simulate the distribution of flow rate of liquid , such as discrete model , differential calculus model and stochastic model . but these models are difficult to calculate or ca n ' t lead to good results
在理论模型方面，前人提出了离散模型、微分模型和随机模型等来模拟液体的径向和轴向流率分布，但仍然存在许多问题，往往计算工作量大且常偏离实际情况，本文作者在导师的指导下，参照前人的研究成果，在滴流床的流率分布中采用了状态离散、时间离散的markov过程描述了滴流床的流率分布，结果与实验值吻合较好。 - Supposed that the fluid in all the fields will accomplish a transport in down - flow distance a z , the flow in trickle - bed is a m step markov process , where m = z / z ( z - the height of trickle - bed ) . according to the theory of random process , the statistic of the markov process will be calculated out from the original distribution and state - transport matrix
假定液体从床层上端面向下流过z距离后，处于各区的流体就实现了一步转移，则可将床内液体的流动视为从一个初始分布开始，经过m步( m = z z ， z为床层高度)转移的状态离散、滴流床流率分布的模拟与整流时间离散的markov过程。 - The random mathematical model is described using equivalent markov equations . the time and state parameters are discrete . based on the model , the flow rate distributions along radial and average at any height can be calculated directly , moreover , the probability transition matrix of the flow can be determined via the statistic character of the random cumulate particles , and be corrected by s . cd the random theoretical model shown in fig . l , the section of the bed of tbr is divided into a series of concentric circles
一、在常温和常压下进行滴流床反应器流率分布的研究，以状态离散、时间离散的齐次markov过程描述了滴流床在滴流区的流率分布，建立了滴流床在滴流区流率分布的随机模型，根据此模型可以： 1 、可直接确定任一高度下的液体径向流率分布及平衡流率分布； 2 、液体流动的概率转移矩阵可由随机堆积颗粒的统计特性确定，以参数s修正。
