摘　　要：微通道反应器是一种利用微细通道和微结构进行反应的装置,具有体积小、反应速度快、产物纯度高、反应效率高等优点,但也有设计制造成本高、热量和质量传递复杂等缺点,因此微通道反应器的结构优化至关重要。为了拓展微通道反应器应用领域,推动微反应器技术的应用。采用拓扑优化技术对微通道反应器进行结构优化,改善微通道反应器内流动均匀性,建立微通道反应器的拓扑优化模型。在进口流速为0.01、0.02、0.03 m/s的情况下对微通道反应器进行优化,共得到12种不同的结构构型,将这12种构型导出建模后进行CFD模拟验证,与传统的Z形多歧管式微通道模型进行对比。拓扑优化模型在进口流速为0.01、0.02、0.03 m/s时较传统模型流动均匀性分别提高了97.85%、97.99%、97.93%,压降降低了3.65%、5.34%、8.34%。拓扑优化模型有利于控制反应物在微通道内的停留时间分布,提高微通道反应器的流动均匀性。Micro-channel reactor is a kind of reaction device using micro-channel and micro-structure,which has the advantages of small size,fast reaction speed,high product purity and high reaction efficiency,but also has the disadvantages of high design and manufacturing cost,complex heat and mass transfer,so the optimization of the structure of micro-channel reactor is very important.In order to expand the application field of microchannel reactor and promote the application of microreactor technology,topology optimization technology was used to optimize the structure of the microchannel reactor and improve the flow uniformity in the microchannel reactor,and establish the topology optimization model of the microchannel reactor.At the inlet flow rates of 0.01,0.02,0.03 m/s,12 different configurations of the microchannel reactor were optimized.These 12 configurations were modeled and verified by CFD simulation,and compared with the traditional Z-shaped multi-manifold microchannel model.When the inlet flow rate of the topology optimization model is 0.01,0.02,0.03 m/s,compared with the traditional model,the flow uniformity of the topology optimization model is improved by 97.85%,97.99%and 97.93%,respectively,and the pressure drop is reduced by 3.65%,5.34%and 8.34%.The topology optimization model is beneficial to control the residence time distribution of reactants in the microchannel and improve the flow uniformity of the microchannel reactor.
