AI Technical Summary

Problems solved by technology

[0003] At present, more experimental and simulated studies on plasma-assisted oxidation, pyrolysis and reforming of gaseous fuels have been paid more attention, while the related studies on liquid fuels are relatively lacking.

In addition, the kinetic enhancement effect of non-equilibrium plasma on combustion is more significant at low temperature. However, due to the complex interaction between plasma reaction and combustion reaction, the current reaction kinetic model still has large uncertainties.
