The growing need for environmental sustainability motivates the search efficient petroleum fuel replacements and additives, which broad reliable property knowledge is desired. In this work, a database of 615 molecules compiled with emphasis on spark-ignition engine applications. considered groups cover alkanes, alkenes, dienes, trienes, aromatics, alcohols, ketones, esters, ethers, furanics, oxygenated benzenoids, nitrogenated components. For each component, physical chemical properties...
Co-design of alternative fuels and future spark-ignition (SI) engines allows very high engine efficiencies to be achieved. To tailor the fuel's molecular structure needs SI with compression ratios, computer-aided design (CAMD) renewable has received considerable attention over past decade. date, CAMD for is typically performed by computationally screening physicochemical properties single molecules against property targets. However, achievable efficiency result combined effect various fuel...
Many studies apply sensitivity analysis to explore the impact of reaction kinetic parameters on model predictions. The importance thermochemical and transport data is often assumed be relatively low. While this true for specific combustion properties hydrocarbons, role in processes nitrogen-containing molecules remains investigated. Thus, work applies adjoint complete set models, i.e., kinetics, thermodynamics, data. This integral approach increases number considered drastically. Compared...
Abstract We present new groups and group values for the gas‐phase thermochemistry of ethers, polyethers, acetals suited combustion modeling. Our investigation comprises fuel species, their primary radicals, peroxy hydroperoxide species. In total, 45 species are used parameterization 14 groups, six which newly introduced here. Presently, calculated at DLPNO‐CCSD(T)/CBS(cc‐pVTZ, cc‐PVQZ) // B3LYP‐D3BJ/def2‐TZVP level theory is combined with from literature. Validation against quantum...
Iso-octane is frequently used as a surrogate fuel or component in primary reference blends when low-temperature combustion strategies engines are investigated. To develop control for these engines, the reaction kinetics of iso-octane must be known starting from low temperatures and intermediate pressures before ignition to high combustion. This work adds new experimental data sets validation mechanism development by investigating oxidation stoichiometric mixtures flow reactor at p = 1, 10,...
