Direct burning of ammonia is required to reduce the consumption fossil fuels. However, has an exceedingly low laminar velocity. Therefore, it necessary improve velocity ammonia. In this study, effect nonequilibrium plasma on problems combustion investigated. To a calculation load from difference time scale, simulation conducted in two stages: section discharge mixture and combustion. The reactions flow reactor are simulated as perfect stirred (PSR) using SENKIN code CHEMKIN-II package....
The total radiative heat flux and the radiation spectra under condition of ammonia fuel combustion in a 10 kW test furnace were measured to clarify characteristics this study. concentration oxygen oxidizer was varied for purpose increasing flame temperature flux. results showed that enriched (30 vol.%) non-premixed formed more than methane/air flame. peak position case shifted downstream region from burner comparison with methane combustion. On other hand, back upstream side
To develop accurate models for the numerical simulation of coal combustion field, detailed experimental data using laser techniques, which can figure out basic phenomena in a flame, are necessary. In particular, soot is one important intermediate substances flame. This paper first world reporting particle size distributions The spatial distribution primary diameter were measured by combination time-resolved induced incandescence (TiRe-LII) method and thermophoretic sampling (TS) method. was...
This work presents experimental observations of strong expanding thermal jets following the application nanosecond spark discharges. These propagate in a toroidal shape perpendicular to interelectrode axis, with high velocities up 30 m s−1 and over distances order cm. Their propagation length is much larger than expansion region produced by conventional millisecond sparks used car engine ignition, thus greatly improving volumetric excitation gas mixtures. The velocity found be fairly...
A microwave-enhanced plasma generation technique was combined with laser-induced ignition to improve characteristics. locally intensified microwave field formed near the breakdown plasma. As absorbed microwaves, emission intensity increased. The lifetime could be controlled by changing oscillation duration. Furthermore, improved minimum energy of methane/air pre-mixture just a small amount energy.
Ammonia is regarded as one of the alternative fuels and a "hydrogen carrier". an easily-liquefiable fuel. Therefore, it suitable fuel for transportation storage. Also, ammonia can be produced in large quantities by using Haber-Bosch process with low price. It known that laminar burning velocity ammonia/air mixture about 10 cm/s at near stoichiometric condition. This very compared other fossil fuels. order to use fuel, necessary improve mixture. In this study, oxygen-enriched combustion was...
The study aims to visualize droplet behaviors of emulsified fuel in secondary atomization a flame stabilized laminar counterflow field. To characteristics the flame, direct photography using color high-speed video camera (7,000 fps) and magnified shadow imaging spray droplets monochrome (180,064 were used. Frequencies also discussed. As result, "bright spots," which similar or higher luminosity than surrounding area observed by around luminous fuel, whereas frequency occurrence spots" was...
In this paper, recent developments of the devolatilization model and soot-formation for numerical simulations pulverized-coal combustion fields, technology used to measure soot particles in fields are reviewed. For development new models, validation developed models using measurement is necessary check accuracy because without have a possibility make large errors simulations. We tabulated process (TDP model) that can take into account effect particle heating rate on volatile matter amount...
