Abstract:As a kind of continuous-flow reactor, the microreactor has been widely used in various organic synthesis reactions. However, the large-scale industrial application of microreactors is difficult because the flow flux is limited by the microscale. In this paper, a high-throughput continuous-flow microreactor was designed based on the idea of embedding three-dimensional spiral components in the channel. The geometric configuration and functional characteristics of the reactor were introduced, and then the convective heat transfer process of the basic unit was simulated by computational fluid dynamics. The results showed that the fluid generates a large number of secondary flows with the action of the internal components, which significantly enhanced the heat transfer process, therefore the temperature in the radial direction of the flow was nearly uniform. The Reynolds number, Prandtl number and geometric structure had significant effects on the heat transfer process. The correlation equations of Nusselt number and friction coefficient were obtained by numerical fitting.
