This work investigates the potential of coconut shell for air-steam gasification using thermodynamic equilibrium model. A thermodynamic equilibrium model considering tar and realistic char conversion was developed using MATLAB software to predict the product gas composition. After comparing it with experimental results the prediction capability of the model is enhanced by multiplying equilibriu...

Laser Induced Breakdown Spectroscopy (LIBS) is a laser based spectroscopic technique which has been used widely in various fields, including the determination of the fuel to air ratio (FAR) in combustion. However, the flames examined so far with LIBS were mostly involving gaseous fuels, lean to stoichiometric compositions, and the burners used were of simple geometry. In the present work, LIBS ...

Time-resolved in situ measurements of thermodynamic properties (pressure, temperature and species density) were performed the annular exhaust a methane-oxygen rotating detonation rocket engine (RDRE) using high-speed laser absorption spectroscopy. Bias-tee circuitry was coupled with distributed feedback quantum cascade near 5 ?m to spectrally-resolve cluster rovibrational transitions fundamenta...

Soot formation is quantified in detail (volume fraction, particle size, number concentration, and light emissivity dispersion exponent) a series of partially premixed counterflow flames ethylene at equivalence ratios, ?, equal to 6.5, 5.0, 4.0, with maximum temperature spanning approximately 200 K. The focus investigate the effect peak ratio on soot while maintaining constant global strain stoi...
