A wave rotor is proposed for use as a constant volume combustor. A novel design feature is investigated as a remedy for hot gas leakage, premature ignition, and pollutant emissions that are possible in this class of unsteady machines. The base geometry involves fuel injection partitions that allow stratification of fuel/oxidizer mixtures in the wave rotor channel radially, enabling pilot igniti...

The high performance and instability in combustion chamber are the most challenging requirements for faster developments and technical advances in most of the engines. The design and development challenges of such engines are highly influenced by its combustion behavior taking place inside the combustion chamber. Studies on the injection, vaporization and combustion phenomena inside combustion ...

The objective this study is to develop materials for production compositions fuel binder, metallic form powders ASD-6 PAP-1. influence amount oxidizer, ...

abstractgiven the importance of the notion of efficiency in the country's economic growth, measuring the efficiency and the technology gap for various industries in order to achieve the best possible resource assignment, following the declared policy goals, is of particular importance for those countries, such as iran, which are now at the early stages of the industrialization process. hen...

Abstract The steady flame propagation through a non-volatile fuel suspension is studied. An Eulerian description used for the gas-phase, while particles are tracked in Lagrangian framework. gas-phase model includes both species transport and energy conservation equations. Moreover, expansion of including particle slip velocity, taken into account. Gas-phase properties realistically dependent on...

I h e interaction of a dense spray diffusion flame with a non-decaying potential vortex has been investigated theoretically. A similwity solution for the local ~tmctiire of the diffusion flamelet in the vortex field has been determined. The global diffusion flame contour generated by the vortcx has been determined by patching the flamelet solutions at different distances from the vortex center ...

The objective of this study is to investigate the combustion in a pilot-ignited supercharged dual-fuel engine, fueled with different types of gaseous fuels under various equivalence ratios. It is found that if certain operating conditions are maintained, conventional dual-fuel engine combustion mode can be transformed to the combustion mode with the two-stage heat release. This mode of combusti...
