Various technological efforts and research are being implemented to ensure emissions from automobile and on-road transportation sources tend towards lower concentrations. This development has resulted in NOx concentration measurements to shift towards near-zero and thus, reach the detection limits of traditional measurement approaches and methods.

Effect of burner geometry on the morphology and propagation of supercritical, CO2-diluted oxy-methane flames in obstructed channels

Advanced combustors are a forefront technology being developed in achieving these next-generation energy systems, which can be adapted towards current thermal power plants. One of such promising advanced energy systems technology is utilization of supercritical carbon dioxide (sCO2)-diluted oxy-methane combustion. The present study therefore scrutinizes the effect of the burner geometry, in particular, the role of the blockage ratio alpha in the propagation and morphology of a CO 2 -diluted oxy-methane flame at a supercritical condition in an obstructed channel with 40% CO 2 -dilution. The computational simulation of the fully-compressible supercritical reacting flow equations is carried out with various blockage ratios, alpha= 1/2, 1/3, 2/3, at constant pressure and temperature. It is observed that with an increase in α, the flame propagat...

From earlier works, the severity of the explosion has been said to depend on various factors such as the ignition location, type of a combustible mixture, enclosure configuration, and equivalence ratio. Explosion venting has been proposed as a safety measure in curbing explosion impact, and the design of safety vent requires a deep understanding of the explosion phenomenon. To address this, the Explosion Venting Analyzer (EVA)—a mathematical model predicting the maximum overpressure and characterizing the explosion in an enclosure—has been recently developed and coded (Process Saf. Environ. Prot. 99 (2016) 167). The present work is devoted to methane explosions because the natural gas—a common fossil fuel used for various domestic, commercial, and industrial purposes—has methane as its major constituent. Specifically, the dynamics of methane-air explosion in vented...
