| 摘 要： | 选用碘化物-碘酸盐体系,利用化学探针法对Side-Tee混合器在较高雷诺数下微观混合效率进行了研究。考察了不同影响参数(如雷诺数、体积流率比、反应物浓度、粘度、管径)对Side-Tee混合器微观混合性能的影响,并用离集指数来表征其微观混合特性。结果表明,雷诺数大于12 000后碘化物-碘酸盐反应体系对混合器内微观混合状况不敏感。基于团聚模型,估算出Side-Tee混合器在实验条件下的微观混合时间为3×10-5~3×10-4s。表明这一型式的反应器对于快速反应尤其是纳米材料制备过程具有替代传统搅拌槽反应器的优势。

| Abstract: | Micromixing efficiency at larger Reynolds number(Re) conditions was investigated in a side tee mixer by using iodide-iodate test reaction as working system,which was characterised by a segregation index XS.Experiments were conducted by considering the effects of Re,flow rate ratio,reactant concentration,viscosity and branch pipe diameter on micromixing efficiency.The results showed that the influence of micromixing to iodide-iodate test reaction was insignificant when Re was larger than 12 000.Based on the ... |
