Internal Temperature Estimation in Microwave Flow Reactors
2020Microwave irradiation is a very effective tool in the field of synthesis because of its rapid heating, etc., based on its energy savings and improvement of selectivity as compared to conventional external heating. In particular, flow-type microwave devices in organic synthesis are suitable for difficult synthesis processes in that the synthesis can be ...

Novel microwave plasma reactor for diamond synthesis
Applied Physics Letters, 1998Numerical simulations were performed to predict the performance of microwave plasma reactors with various reactor geometries. The simulations include the calculation of the electric field distribution using the finite integration theory and the determination of the plasma density distribution based on a breakdown field algorithm.

Electromagnetic Relationship between Microwaves and Flow Reactor Systems
The Chemical Record, 2018AbstractOne of the important points in handling microwaves is that the order of magnitude is decimeter order. Laboratory equipment is not too big for wavelength, so intensity nonuniformity may occur. Another important point is that microwave propagation changes with material parameter changes.

Modeling of microwave reactors : microwave and kinetics in gas flow approaches
Le Journal de Physique IV, 1998The modeling of microwave plasma reactors must couple the external hf field to the kinetics of charged particles and neutral species in presence of a gas flow. Various approaches to solve the non-linear coupled equations which describe the physical situation, are proposed and discussed in this paper.

Modelling and simulation of microwave plasma reactor
Plasma Devices and Operations, 2004Using the Finite Integration Technique, we have simulated electromagnetic field distributions in the microwave plasma reactor. The relationship between electric field distribution and the length of antenna inserted into the microwave plasma reactor has been simulated. The effect of the length of antenna inserted into the microwave plasma reactor on the
