| Abstract: |
| The rapid development of continuous flow micro-reactors provides an accurate control path for chemical synthesis technology.The fluid flow,the component mixing and the mass transfer in a micro-reactor are the physical basis of reaction.To some extent,the strengthening of the mass transfer can reasonably improve the mixing effect,increase the components contact area,reduce the size of the micro-reactor,and shorten the molecular diffusion distance.Through improving the configuration of the micro mixer and introducing pulsed flow,the convection and mass transfer can be effectively improved and the reaction can be affected.To quantitatively analyze these effects is the basis of enhancing mass transfer and optimizing the reaction process.In this paper,an effective lattice Boltzmann model about the virtual serial competitive reaction is proposed.The flow field structure,mass mixture,mass transfer and chemical reaction in the Y-type and inverted-Y-type micro-reactors are numerically studied through this model.The effects of pulsed flow on mass transfer and chemical reaction under different flow field configurations are quantitatively analyzed.The conclusion is a significance reference of the micro-reactors design and its precise control. |
