The use of ammonia and hydrogen as fuels to decarbonise the heavy transport industry has attracted worldwide attention. In this work, a swirl-enhanced combustion test rig been built investigate emission characteristics non-premixed ammonia/hydrogen flames. blowoff limits were first examined ensure that range stable flames could be achieved. Emissions containing nitric oxide (NO), nitrous (NO2), slip (NH3) unburnt (H2) then measured with variety global equivalence ratios, blending inlet gas...
Abstract Maritime shipping is a key component of the global economy, representing 80–90% international trade. To deal with energy crisis and marine environmental pollution, hydrogen-natural gas-diesel tri-fuel engines have become an attractive option for use in maritime industry. In this study, numerical simulations experimental tests were used to evaluate effects different hydrogen ratios on combustion emissions from these engines. The results show that, terms performance, as proportion...
Ammonia, as a hydrogen carrier and an ideal zero-carbon fuel, can be liquefied stored under ambient temperature pressure. Its application in internal combustion engines holds significant potential for promoting low-carbon emissions. However, due to its unique physicochemical properties, ammonia faces challenges achieving ignition when used single fuel. Additionally, the presence of nitrogen atoms results increased NOx emissions exhaust. High-temperature selective non-catalytic reduction...
In this paper we present an improved P-stable trigonometrically fitted Obrechkoff method with phase-lag (frequency distortion) infinity. Compared the previous developed by Simos, our new is simpler in structure and more stable computation. We have also accuracy of first-order derivative formula. From numerical illustration presented, can show that much accurate than methods.
We present an improved space-discretization scheme for the numerical solutions of time-dependent Schr\"odinger equation. Compared to W. van Dijk and F. M. Toyama [Phys. Rev. E 75, 036707 (2007)], one, which contains more terms second-order partial derivatives, greatly reduces error resulting from spatial integration. For a $(2l+1)$-point formula with $(2l+1)$ local truncation can decrease order ${(\ensuremath{\Delta}x)}^{2l}$ ${(\ensuremath{\Delta}x)}^{4l}$, while previous one only term...
In this paper we present a new kind of P-stable eighteenth-order six-step method for periodic initial-value problems. We add the fourth derivatives to our previous increase accuracy. apply two classes well-known problems and compare it with methods. The numerical results show that is much more stable, accurate efficient than
Abstract Liquid flow distribution has been a major concern when scaling up random packed columns. This study concerns the measurements of liquid in large scale column with 25.4 mm stainless steel Pall rings. The was studied bed height from 0.9 to 3.5 m, rate 2.91 6.66 kg/m 2 ·s, and gas 0 3.0 ·s. In addition, three systems, water/air, aqueous detergent solution/air Isopar/air, were used effect physical properties on distribution, two different distributors employed test distributor design....
Transitions associated with the vibrations ν₁, ν₁ + ν(b)¹, ν₅¹, and ν₅¹ - of complex OC···Cl₂ have been rovibrationally analyzed for several isotopologues involving isotopic substitutions in Cl₂. Spectra were recorded using a recently constructed near-infrared (4.34 to 4.56 μm), quantum-cascade laser spectrometer cw supersonic slit jet expansion. Spectral analysis allowed precise determination intermolecular vibration OC-³⁵Cl₂ be 25.977637(80) cm⁻¹. These results incorporated other...
The ambitious new International Maritime Organization (IMO) strategy to reduce greenhouse gas emissions from ships will shape the future path towards decarbonization of fleet and bring further ecological challenges. In order replace larger oil-based part marine fuel with components renewable sources, it is necessary develop multi-component blends. this work, biomethanol biodiesel two additives—dodecanol 2-ethylhexyl nitrate—in 20 blends diesel oil (MDO) were selected as alternative pure...
With increasing environmental pollution from ship exhaust emissions and increasingly stringent International Maritime Organization carbon regulations, there is a growing demand for cleaner lower-carbon fuels near-zero-emission marine engines worldwide. Liquefied natural gas low-carbon fuel, when liquefied (LNG) used on ships, dual-fuel methods are often used. The pre-chamber plays key role in the working process of engines. In this paper, an effective three-dimensional simulation model based...
Currently, in the two technological approaches for using diesel pilot injection to ignite methanol and partially substituting fuel with methanol, neither can fully achieve carbon neutrality context of internal combustion engines. Compression-ignition direct-injection marine engines exhibit significant application potential because their superior economy lower emissions. However, low cetane number coupled its high ignition temperature latent heat vaporization, poses challenges, especially...
