This study aims to develop general design rules for gas-liquid Taylor flow T-junction microreactors. Two major issues to address are the relationship between gas flow rate and pressure drop, and the bubble generation and hydrodynamics in different devices. A dimensionless relationship between gas pressure and flow rate is proposed, along with a model to predict bubble generation and investigate hydrodynamics. Lastly, a design procedure for gas-liquid Taylor flow T-junction microreactors is proposed.
There are many studies on the gas-liquid Taylor flow in T-junction microdevices, but the general design rules for gas-liquid microreactors are not well developed. This work is trying to develop a general design method for gas-liquid Taylor flow T-junction microreactors. Two significant issues must be addressed for the design, which are to determine the relationship between the gas flow rate and the pressure drop in the microreactor, and to know the bubble generation and hydrodynamics of the Taylor flow in different devices. For the first issue, a dimensionless relationship between the gas pressure and the gas flow rate is proposed by determining the pressure drop. For the second issue, a model based on energy efficiency is developed to predict the bubble generation process behavior which can be adapted to different devices. The hydrodynamics in different devices are also investigated. Lastly, a procedure is proposed for the design of gas-liquid Taylor flow T-junction microreactors.
