In the current work, effect of H2O2 addition on flame structure, laminar speed and NOx emissions is investigated in context 1D premixed H2/air flames at Tu = 300 600 K, p 1 30 atm, ? 0.5. Mathematical tools from computational singular perturbation approach are used order to identify key chemical transport mechanisms. The causes a significant increase (sL), heat release (Q) emissions. Indicative...

Trace organic compounds (TrOCs), mostly found in secondary effluents, have a potential impact on the environment, affecting surface water, groundwater, and especially aquatic ecosystems. The present study focuses on oxidation of five selected TrOCs in column experiments, by simulating Soil Aquifer Treatment (SAT) integrated with Fenton-like reaction, using Granular Ferric Hydroxide (GFH) as a c...

Hydrogenated small fullerenes (Cn, n < 60) are of interest as potential astrochemical species, and intermediates in hydrogen-catalysed fullerene growth. However, the computational identification key stable species is difficult due to vast configurationally space structures. In this study, we explored routes predict hydrogenated fullerenes. We showed that neither local geometry nor electronic...

The preparation of air–fuel mixture is considerably dependent on fluid flow dynamics to achieve improved performance, efficiency, and engine combustion in the appearance of flow. In this study, the effects of mixtures of hydrogen and compressed natural gas (CNG) on a spark ignition engine are numerically considered. This article presents the results of a direct-injection engine using methane–hy...
