Heat Transfer in Microreactors

This lecture covers the concept of narrowing Residence Time Distribution (RTD) in segmented flow microreactors by using gas-liquid or liquid-liquid systems to generate fluid-fluid slugs, which travel through the system to suppress axial dispersion. It also discusses the importance of surface wettability in RTD, the mechanisms to improve RTD in microreactors, and the heat transfer in microchannels for homogeneous and segmented flows. The instructor explains the reaction classes, heat production, and heat management strategies for different types of reactions, emphasizing the critical role of heat evacuation and hot spot reduction in microreactors.
