基于拓扑优化方法的微通道反应器流动均匀性优化
Flow uniformity optimization of microchannel reactor based on topology optimization method
摘要
Abstract
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.关键词
