“…The spray areas and volumes of E10 and W10 are roughly the same, but they are less than that of D100. Specifically, at 1500µs, the spray volumes of E10 and W10 are 22764 and 21926 mm 3 respectively, which are 18% and 21% smaller than that of D100 (27725mm 3 ). This indicates that the higher viscosities of E10 and W10 result in weaker spray expansion capacities of E10 and W10 sprays, which is consistent with the thinner spray structure of E10 and W10 shown in Fig.…”

“…The research on alternative fuels in internal combustion engines (ICE) has become one of the hot spots due to the increasing serious environmental and energy problems [1,2]. Using alternative fuels can not only partially replace the traditional fossil fuels and alleviate the dependence on them [3,4], but also reduce the pollutant emissions from ICEs [5,6], making it one of the most promising methods to save energy and reduce emissions.…”

“…Table 2 below shows the fuel atomization and spray models applied in this article. As for the numerical simulation of marine diesel engines, n-heptane [41][42][43][44][45] and ntetradcane [46][47][48] are commonly taken as surrogate fuels for heavy fuel oil. In this article, n-heptane is taken as surrogate fuel.…”

A computational fluid dynamics model of the marine diesel engine was established and validated, and the simulation studies were carried out using this model. Different gravity conditions were set in the computational fluid dynamics model to investigate their effect on marine diesel emissions and performance. By comparing the simulation results under different basic grid sizes, 1.2 mm was selected as the basic grid size of the computational fluid dynamics model. The model uses the experimental data including cylinder pressure, heat release rate, and nitrogen oxides (NO x) emissions to calibrate and validate the model. The simulation results are very close to the experimental data, and slight errors are also within the allowable range. In particular, when considering the heat transfer of the combustion chamber wall, the simulation results of the heat release rate are closer to the experimental data. The simulation results show that gravity has a slight effect on cylinder pressure and heat release rate, and has a certain degree of effect on fuel spray and atomization. The penetration length of the fuel is proportional to the gravity, and the maximum deviation of the Sauter mean diameter of the droplet is 25.74%. The spray and atomization process of fuel directly affects combustion and emissions. The maximum deviation of NO x emissions is 6.03%, which is reduced from 7.46 to 7.01 g/kW·h. Finally, the three-dimensional simulation results of temperature, equivalence ratio, and NO x emission of different crank angles under different gravity conditions are compared.

“…The application of single-component surrogate fuels, such as n-heptane for Diesel combustion kinetics [21][22][23] and n-dodecane for Diesel fuel physical properties [24][25][26], are well- Recent work has increased the number of well-characterized hydrocarbons that are representative of Diesel fuel and potentially useful as surrogate fuel components [8,18,[27][28][29][30][31]. These efforts have enabled the development of multi-component surrogate fuels that can more closely replicate the properties of Diesel fuel [32][33][34][35][36][37][38][39][40]. However, as researchers strive to match the combustion and physical properties of Diesel fuel, the complexity of multi-component surrogate fuels has greatly increased.…”

Diesel fuel is composed of a complex mixture of hundreds of hydrocarbons that vary globally depending on crude oil sources, refining processes, legislative requirements and other factors. In order to simplify the study of this fuel, researchers create surrogate fuels to mimic the physical and chemical properties of Diesel fuels. This work employed the commercial software Reaction Workbench-Surrogate Blend Optimizer (SBO) to develop a Surrogate Fuel Library containing 18 fuels. Within the fuel library, the cetane number ranges from 35 to 60 (in increments of 5) at threshold soot index (TSI) levels representative of low, baseline and high sooting tendency fuels (TSI = 17, 31 and 48, respectively). The Surrogate Fuel Library provides the component blend ratios and predicted properties for cetane number, threshold soot index, lower heating value, density, kinematic viscosity, molar hydrogen-to-carbon ratio and distillation curve temperatures from T10 to T90. A market petroleum Diesel fuel with a cetane number of 50 and a threshold soot index of 31 was selected as the Baseline Diesel Fuel. The combustion, physical and chemical properties of the Baseline Diesel Fuel were precisely matched by the Baseline Surrogate Fuel. To validate the SBO predicted fuel properties, a set of five surrogate fuels, deviating in cetane number and threshold soot index, were blended and examined with ASTM tests. Good agreement was obtained between the SBO predicted and ASTM measured fuel properties. To further validate the Surrogate Fuel Library, key properties that were effected by altering the component blend ratios to control cetane number and TSI were compared to a set of five market Diesel fuels with good results. These properties included density, viscosity, energy 2 density and the T10 and T90 distillation temperatures. The Surrogate Fuel Library provided by this work supplies Diesel engine researchers and designers the ability to analytically and experimentally vary fuel cetane number and threshold soot index with fully-representative surrogate fuels. This new capability to independently vary cetane number and threshold soot index provides a means to further enhance the understanding of Diesel combustion and design future combustion systems that improve efficiency and emissions.
