| 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。

| Abstract: | 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 ... |
