Residence Time Distribution in Microreactors

This lecture covers the residence time distribution (RTD) in microreactors, focusing on topics such as the effect of radial dispersion, flow maldistribution, and axial dispersion. It discusses the Taylor-Aris correlation, molecular diffusion, and the impact of different geometries on RTD. The lecture also explores RTD in coiled tubes, segmented flow, and the enhancement of Bo by secondary radial flow. Various strategies to improve RTD in microreactors are presented, including the use of fixed beds, static mixers, and chaotic microreactors. Heat transfer in microreactors is discussed, emphasizing heat management for different types of reactions and the importance of heat evacuation. The lecture concludes with insights into heat transfer mechanisms in straight micro-channels and the design considerations for optimizing heat transfer in microreactors.
