Field-emission plasma enhancement of H2–O2 micro-combustion

Theory of magnetic-field enhancement of surface-field terahertz emission

We present a theoretical treatment of surface–field THz generation in semiconductors, which explains the power enhancement observed when a magnetic field is applied. Our model consists of two parts: a Monte Carlo simulation of the dynamics of carriers generated by a subpicosecond optical pulse, and a calculation of the resulting THz radiation emitted through the semiconductor surface. The magne...

Combustion and Exhaust Emission Characteristics of Diesel Micro-Pilot Ignited Dual-Fuel Engine

Plasma-assisted combustion*

This paper presents an overview of experimental and numerical investigations of the nonequilibrium cold plasma generated under high overvoltage and further usage of this plasma for plasma-assisted combustion. Here, two different types of the discharge are considered: a streamer under high pressure and the so-called fast ionization wave (FIW) at low pressure. The comprehensive experimental inves...

Demonstration of Field Emission Cathode Operation in a Plasma Environment

Field emission cathodes are being considered for use on low-power electrostatic and electromagnetic propulsion systems as well as on electrodynamic tether systems. In these systems, field emission cathodes prevent negative spacecraft charging by emitting a lowpower electron beam that is accommodated by the ambient plasma. Prototype cathodes were tested at the University of Michigan as part of a...

Enhancement of Combustion and Flame Stabilization Using Stabilized Non-Equilibrium Plasma

The effect of a stabilized non-equilibrium gliding arc plasma discharge on the stabilization and extinction of nitrogen diluted, methane/air counterflow diffusion flames was investigated both experimentally and numerically. To quantify the effect, extinction limits and flame temperature profiles via Rayleigh scattering were measured, calculated and compared to numerical simulations using detail...
