摘要: 本文利用马尔柯夫过程理论,建立了一个包括气泡上升速率、气泡大小以及气泡在床内出现位置的随机模型.利用热力学理论分析了模型参数.同时,本文利用四组元组合电导探针测定了气泡大小及其分布密度,验证了随机模型.结果表明,模型值与实验拟合很好.
Abstract: In this paper, the theory of Markov chain is used to discuss the behavior of bubbles in G-L-S fluidized bed. A generalized stochastic model is proposed. On the basis oi thermodynamics, the model parameters were analysed and discussed to obtain a simplified stochastic model of bubble size distribution. In addition, the distribution of bubble size in a twodimensional G-L-S three-phase fluidized bed were measured by using conductivity probe method and micro-computer sampling technique. The calculated values with the stochastic model were very close to the experimental data.
