| 摘 要： | 在ＩＰＳＡＲ算法基础上，推导了适用于考虑浓度变化影响的浓密液固两相流动数值计算的ＤＩＰＳＡＲ算法，并考虑了颗粒湍流强度梯度传输对颗粒浓度分布的影响，对竖直上升管中浓密液固两相流动分别采用ＩＰＳＡＲ和ＤＩＰＳＡＲ算法进行了数值计算和理论分析，结果表明，ＤＩＰＳＡＲ算法能更有效地预测浓密液固两相流动．

| Abstract: | In this paper, a DIPSAR alogorithm for dense liquid solid two phase flow is developed and the influence of particle turbulence intensity to the distribution of particle concentration is accounted for. A numerical computation for dense liquid solid two phase upflow in a pipe and a comparison of DIPSAR algorithm with IPSAR are performed. The results show that DIPSAR algorithm is better than IPSAR algorithm. |
