Catalytic partial oxidation (CPOX) has recently received particular attention because it is one of the most attractive technologies for the production of syngas and hydrogen in small to medium scales. Current study subjected to partial oxidation reforming which have simultaneously studied the effect of the fuel composition and flow rates of methane-oxygen mixed gas on the SOFCs performances. In...

Whether steady-state gaseous microgravity spherical diffusion exist in the presence of radiation heat loss is an important fundamental question and has implications for spacecraft fire safety. In this work, experiments aboard International Space Station a transient numerical model are used to investigate existence flames. Gaseous flames stabilized on porous burner employed normal (i.e., fuel fl...

The impact of soil management practices on ammonia oxidizer diversity and spatial heterogeneity was determined in improved (addition of N fertilizer), unimproved (no additions), and semi-improved (intermediate management) grassland pastures at the Sourhope Research Station in Scotland. Ammonia oxidizer diversity within each grassland soil was assessed by PCR amplification of microbial community...

Mo17O47 nanowire-arrays are promising active materials and electrically-conductive supports for batteries and other devices. While high surface area resulting from long, thin, densely packed nanowires generally leads to improved performance in a wide variety of applications, the Mo17O47 nanowire-arrays synthesized previously by electrically-heated chemical vapor deposition under vacuum conditio...

This article explores the throttling aspect of hybrid rocket motor through experiments using a lab-scale motor. The utilizes wax-Al based fuel and compressed air as oxidizer. oxidizer flow rate was modulated PID controller to study closed-loop thrust control performance Numerical simulations cold tests were carried out identify suitable gains for algorithm. Pressure feedback used in algorithm o...

Lagrangian PDF investigations are performed of the Sandia piloted flame E and the Cabra H2/N2 lifted flame to help develop a deeper understanding of local extinction, re-ignition and auto-ignition in these flames, and of the PDF models’ abilities to represent these phenomena. Lagrangian particle time series are extracted from the PDF model calculations and are analyzed. In the analysis of the r...
