The aim of this research is to investigate the effects a direct current (DC) electric field on combustion behavior co-flow propane diffusion flame. flame length and NOx emission were observed measured. enhances process by causing movement ions molecules in flame, resulting change shape heights decrease with an increase applied voltage polarity, more dominant effect be positive DC field. However...

Furrow irrigation proceeds under several soil-water-furrow hydraulics interaction dynamics. The soil erosion consequences from such interactions in furrow irrigation in Samaru had remained uncertain. A furrow irrigation-induced erosion (FIIE) model was used to simulate the potential severity of soil erosion in irrigated furrows due to interactive effects of infiltration rates, land slope, and s...

We discuss the stability of homonuclear and heteronuclear mixtures of 3He and 4He atoms in the metastable 2 S1 state (He∗) and predict positions and widths of Feshbach resonances by using the asymptotic-bound-state model. All calculations are performed without fit parameters, using ab initio calculations of molecular potentials. One promising very broad Feshbach resonance ( B = 72.9+18.3 −19.3 ...

Flashing or thermodynamic breakup of a liquid jet occurs when a pressurized subcooled or saturated liquid is released to a lower pressure, resulting in violent vapor nucleation, expansion, and break up of the liquid phase. Flashing is known to produce very fine droplet atomization, often not possible by traditional mechanical means. In this work, flashing atomization is introduced in a spray bu...

We examine the combustion of mixed H2-CH4-air fuels using two-dimensional simulations that incorporate detailed kinetics and a mixture-averaged model for differential species transport. The mixtures range from lean H2-air at φ=0.37 to lean CH4-air at φ=0.7. For each mixture, we compute the quasi-steady propagation of a flame into flow with superimposed low-level turbulent fluctuations. We exami...

Few-layer graphene is grown on copper and nickel substrates at high rates using a novel flame synthesis method in open-atmosphere environments. Transmittance and resistance properties of the transferred films are similar to those grown by other methods, but the concentration of oxygen, as assessed by X-ray photoelectron spectroscopy, is actually less than that for graphene grown by chemical vap...
