摘　　要：针对光催化制氢反应器内液固两相流的特点,运用代数滑移模型,对反应器内的催化剂颗粒-水两相流动进行了数值模拟。采用分块的结构化网格,并运用多重网格方法进行求解。通过与前人实验中压力梯度结果的比较,对模型进行了验证,并最终得到了反应器内催化剂颗粒的典型分布及相应的类型图。According to the characteristics of the catalyst-liquid two-phase flow in photocatalytic reactor for hydrogen production, an algebraic slip model has been selected to investigate the catalyst particle distributions. A block-structured non-uniform grid was applied to discretize the entire domain and an algebraic multi-grid （AMG） method was used to solve the pressure field. And the model was verified by comparisons of mean slurry pressure gradients with the experimental data in the former literature. The catalyst distributions and corresponding type map were obtained.
