摘要
Abstract
A novel microchannel reactor was developed incorporating a specially designed two-layer feed T-shaped inlet(TLFT)and a spiral channel based on an Archimedean spiral configuration.To comprehensively evaluate the reactor's performance,a new metric—reaction efficiency energy ratio(REER)—was proposed,which accounted for both reactant conversion and energy consumption.A numerical model for a homogeneous reaction was established and computational fluid dynamics(CFD)simulations were performed using Fluent software across a Reynolds number(Re)range of 1-300 to investigate the flow and reaction behaviors within the reactor.Reaction enhancement mechanisms were elucidated by identifying two dominant flow features:The synergy between vortices and fluid contact surfaces at low Re,and a four-vortex structure induced by flow direction reversal at high Re.The proposed reactor was benchmarked against three conventional microchannel designs-T-shaped spiral,cross-shaped spiral and TLFT-shaped serpentine channels with identical curvature radii.Simulation results demonstrated that the REER of the novel reactor was 28.6%,18.4%and 8.6%higher than those of the T-shaped spiral,cross-shaped spiral and TLFT-shaped serpentine reactors,respectively,highlighting the superiority performance of the new microchannel configuration.关键词
