A wide-range experimental and theoretical investigation of ammonia gas-phase oxidation is performed, a predictive, detailed kinetic model developed.
The influence of the addition ammonia on oxidation methane was investigated both experimentally and numerically. Experiments were carried out at atmospheric pressure, using a fused silica jet-stirred reactor, recrystallized alumina tubular reactor designed purpose to reach temperatures as high ∼2000 K. A temperature range 600–1200 K in residence time 1.5 s, while experiments flow between 1200 2000 K, for fixed about 25 ms reactive zone. methane/ammonia mixture, diluted helium, used reactors...
Fast-pyrolysis bio-oils (FPBOs) obtained from lignocellulosic biomass are gaining attention as sustainable fuels for various applications, including the transport sector and power production. A significant fraction of is constituted by nitrogen-containing compounds (N fuels) that should be considered when developing surrogate models FPBOs. Moreover, content N in FPBOs expected to strongly contribute production nitrogen oxides (NOx) directly fuel-bound (fuel NOx), addition thermal NOx...
The influence of the main process parameters on oscillatory behavior methane oxidation was analyzed in conditions relevant for low-temperature combustion processes. investigation performed by means direct comparisons between experimental measurements realized two jet-stirred flow reactors used at atmospheric pressure. With operating systems coupled, wide ranges inlet temperature (790–1225 K), equivalence ratio (0.5 < Φ 1.5), mole fraction (XCH4 from 0.01 to 0.05), bath gases (i.e., He, N2,...
The stable operation of low-temperature combustion processes is an open challenge, due to the presence undesired deviations from steady-state conditions: among them, oscillatory behaviors have been raising significant interest. In this work, establishment limit cycles during hydrocarbons in a well-stirred reactor was analyzed investigate role chemistry such phenomena. An experimental investigation methane oxidation dilute conditions carried out, thus creating quasi-isothermal and decoupling...
The effect of high H2O concentration during oxy-steam combustion on the oxidation methane and ammonia was investigated both experimentally numerically. Comparison experiments between O2/N2 O2/H2O atmosphere were performed in a flow reactor at atmospheric pressure covering fuel-rich to fuel-lean equivalence ratios temperatures from 973 1773 K. Experimental results showed that presence dramatically suppressed CO formation above 1300 High concentrations inhibited NO under stoichiometric...
When you reach with your straw for the final drops of a milkshake, liquid forms train plugs that flow slowly initially because high viscosity. They then suddenly rupture and are replaced rapid airflow characteristic slurping sound. Trains also observed in complex geometries, such as porous media during petroleum extraction, microfluidic two-phase flows, or flows pulmonary airway tree under pathological conditions. The dynamics events these geometries play dominant role spatial distribution...
The ignition delay times (IDTs) of iso-octane with or without exhaust gas recirculation (EGR) in the 600–950 K temperature range and at pressures 20 30 bar were measured under various equivalence ratios (Φ = 0.6–1.4) aid a rapid compression machine. As for neat IDTs measurements bar, it was found that obtained this work consistent ones by other groups. Notable prolonging effects can be seen negative coefficient region EGR, which is independent ratios. Moreover, EGR fuel-rich stoichiometric...
The RANS (Reynolds-averaged Navier–Stokes equations) with CFD (Computational Fluid Dynamics) simulation method is used to analyze the head hump formation mechanism in double-suction centrifugal pump under a part load condition. purpose establish clear connection between and microcosmic flow field structure, reveal influence them. It found that diffuser stall causes change impeller capacity for work, this most critical reason formation. hydraulic loss of volute also hump, it analyzed using...
In this study, the effect of mainstream velocity on optimization a fan-shaped hole flat plate was experimentally investigated. The experiment conducted by changing forward expansion angle (βfwd), lateral (βlat), and metering length ratio (Lm/D) film-cooling hole. A total 13 cases extracted using Box–Behnken method were considered to examine shape parameters under 90 m/s condition, results compared with derived 20 m/s. One density (DR = 2.0) blowing (M) ranging from 1.0 2.5 considered,...
CO-SCR reaction, capable of simultaneously removing NO and CO from vehicle exhaust gases, has garnered significant attention. PGM (platinum group metal) catalysts are still the preferred choice due to their...
The inner surface of lung airways is covered by a thin layer mucus whose thickness usually about 2 or 3% the total radius duct. However certain diseases like asthma, chronic bronchitis allergies can induce hypersecretion mucus, leading to formation liquid plugs which occlude airways. These considerably alter distribution air during breathing cycle. It therefore fundamental understand propagation in presence such and particular airway reopening. Some studies have been performed on real lungs...
