Multi-scale modeling of nanosecond plasma assisted combustion
… effect of temperature on fuel-air ignition and combustion (thermal effects) have been widely studied and well understood. However, a comprehensive understanding of nonequilibrium plasma effects (in situ generation of reactive species and radicals combined with gas heating) on the combustion …

Non-thermal plasmas in flames and other inhomogeneous environments
Non-thermal plasmas in non-uniform gases appear in several technological applications (plasma assisted combustion and aerodynamics, and plasma jets), as well as in natural phenomena (sprites). Whereas in the case of plasma jets and sprites this problem has captured significant attention, the …

Exergetic Analysis Of Hydrogen Combustion Involving Electronically Excited Species
<p>Plasma-assisted combustion (PAC) is a growing field of research that involves using nonthermal plasma (NTP) to enhance combustion. PAC research involves modeling reaction mechanisms and chemical kinetics. Exergy analysis of combustion devices focuses on combustion irreversibility, including …

Ignition by Nanosecond Repetitively Pulsed Discharges
Previous works have shown that nanosecond pulsed plasmas can have strong benefits on ignition, including a reduction of ignition delay times, a decrease of minimum ignition energies, or an extension of lean ignition limits. These effects are highly dependent on experimental conditions such as …

Plasma Assisted Ignition in a Three-dimensional Scramjet Combustor with a Photon-preserving Radiation Model
This thesis studies how plasmas created by nanosecond repetitive pulsed discharges (NRPD) can affect and improve the combustion characteristics in a high-speed fluid flow that simulates scramjet conditions. This is done by creating a computational code that incorporates the effects of plasmas, …

Nanosecond Pulsed Plasmas in Dynamic Combustion Environments
Plasma assisted combustion (PAC) is a promising technology for extending combustion operating envelopes with a low energy cost relative to flame power. It has been investigated for use in various situations, particularly those where combustion is being performed near flammability limits imposed by …
