About the Project
Plasma-assisted combustion is a promising technique to improve engine efficiency, reduce emissions and enhance fuel reforming. Ignition and combustion control using cold and non-thermal plasmas appearing in microwave discharges has become a major topic of interest. Microwave discharges are widely used for generation of quasi-equilibrium and non-equilibrium plasma. Among the various types of discharges studied, the microwave streamer discharge has recently demonstrated promising characteristics for ignition at low initial temperatures. The streamer discharge looks as a chaotic structure of plasma channels (filaments). Their characteristic diameter is about a fraction of millimetre, and a characteristic distance between the channels is a fraction of wavelength. A streamer filament divides itself into several branches that connect to each other forming a net of thin plasma filaments, whose characteristic length is related to electro-dynamic resonance effects. A local initiation of such a discharge is provided by special facilities.
In this project, possibilities of the use of microwave radiation to initiate combustion of air/fuel mixtures are investigated. Premixed flame propagation of air/propane mixture is investigated through a numerical simulation using Navier-Stokes equations coupled with chemical reactions. The results of computational studies of combustion of air/fuel mixture are compared with the available experimental data.
There is no funding for this project: applications can only be accepted from self-funded candidates
