Experimental Investigation on Flow Characteristics and Ignition Performance of Plasma-Actuated Flame Holder
نویسندگان
چکیده
Improving the performance of flame holders has been a key focus research on ramjet combustors. The plasma actuator potential to improve ignition by manipulating flow field holder. In this study, plasma-actuated holder was designed. aim study is combustor applying discharge aerodynamic effects and were investigated. results demonstrated that induced jet direction surface arc perpendicular actuator. dissipated faster at lower pressures. actuation intensity area increased with number channels discharges. Increasing frequencies can increase times height. under microsecond pulse duration better than those nanosecond duration. Actuators installed inside showed outside. Under different total temperature conditions, significantly extended pressure limit combustion efficiency 9.12% 4.3% average, respectively.

In this paper, the effect of air turbulence intensity on the flame structure in various radii and lengths of a flame holder numerically studied. Finite volume method is used to solve the governing equations. The obtained numerical results using realizable k-ε and β-PDF models show a good agreement with the experimental data. The results show that flame holder with greater lengths yield shorter ...

Premixed flame ignition by transient plasma discharges
Flame ignition by short-duration (≈ 50 ns) transient plasma, or corona, discharges was investigated for methane-air, propane-air and butane-air mixtures at atmospheric and elevated pressures. Such discharges produce a larger fraction of high-energy electrons, yield more spatially distributed energy and deposit energy in the gas more efficiently than conventional arc discharges do. We show that ...
