“…Recognizing that surrogate models can be a powerful tool to the screening process by reducing the number of expensive full-scale rig and engine tests required to certify a candidate jet fuel, recent progress has been contributing to surrogate formation for alternative jet fuels. Table 5 summarizes recent developments of surrogates for alternative jet fuels [98,[113][114][115][121][122][123][124]. It is seen that based on different intended applications for various alternative jet fuels, their surrogates can differ significantly in the compositions and validation targets, as well as the methodologies with which they were formulated.…”

“…Other studies on surrogate formulation for alternative jet fuels are also noted. Slavinskaya et al [124] used an optimization method with a similar set of criteria as Naik et al [113] to propose surrogates for synthetic GTL, while Mzé-Ahmed et al [103] and Dagaut et al [115] proposed their surrogates based on matching the oxidation species with those of the target alternative jet fuels. It is of interest to point out that both [103] and [115] suggested the inclusion of cycloparaffins and aromatics in their surrogate composition.…”

With the growing air transport demand and concerns about its environmental impacts, alternative jet fuels derived from non-conventional sources have become an important strategy for achieving a sustainable and green aviation. In the past ten years, governments around the world along with aviation industry have invested significant efforts into exploring all sorts of alternative jet fuels that can be used to power aircraft engines. Among all the alternative jet fuels explored, the aviation sector has agreed that hydrocarbon-based ‗drop-in' replacement fuels, which are fully interchangeable and compatible with current conventional jet fuels, would be the best choice in the near future, as they can be used without any modifications to today's aircraft or fuel infrastructure. This paper reviews the current state of development of ‗drop-in' alternative jet fuels including various Fisher-Tropsch synthetic jet fuels and bio-jet fuels. Recent advances in research activities on alternative jet fuels, including fuel property evaluations, combustor component tests, engine tests, and flight tests, are highlighted. Furthermore, basic research needs for understanding the combustion characteristics of alternative jet fuels are underlined and discussed by reviewing recent fundamental combustion studies on ignition, extinction, flame

“…More recently, a comprehensive review of diesel surrogate research appeared in 2011 [175], and another work further emphasized the need for and complexity of representing physical properties of aviation gas turbine fuels [176]. Tools for estimating physical properties of components and mixtures were advanced substantially in sophistication [177], and the resulting criteria were applied to evaluate the "physico-chemical authenticity" of a number of previously proposed jet fuel surrogates [178,179].…”

Internal combustion engines running on liquid fuels will remain the dominant prime movers for road and air transportation for decades, probably for most of this century. The world's appetite for liquid transportation fuels derived from petroleum and other fossil resources is already immense, will grow, will at some future time become economically unsustainable, and will become infeasible only in the very long term. The ongoing process of augmenting and eventually replacing petroleum-derived fuels with liquid alternative fuels must necessarily involve approaches that result in comparatively much lower net carbon cycle emissions from the transportation sector, most likely through a combination of carbon sequestration and renewable fuel production. The successful growth and establishment of a sustainable, profitable alternative fuels industry will be best facilitated by approaches that integrate alternative products into petroleum-derived fuel streams (i.e., gasolines, diesel, and jet fuels) and consider synergistic evolution of and integration with prevailing refining and liquid fuel distribution infrastructures. The emergence of low temperature combustion strategies, particularly those implementing dual fuel methods to achieve Reaction Controlled Compression Ignition (RCCI), offers the potential to significantly improve operating efficiency and reduce emissions with minimal aftertreatment. For all advanced combustion engine technologies, but especially for RCCI, a clear understanding of fuel property influences on combustion behaviors will be important to achieving projected engine performance and emissions. To achieve the benefits projected by emerging engine technologies, the properties of petroleumderived fuels themselves must be modified over time, but the effects of blending candidate alternative fuels with these conventional fuels must also be understood. Predicting the coupled physical and chemical property effects of real fuels on energy conversion system performance and emissions is a daunting problem, even for petroleum-derived real fuels, since each is composed of several hundred to thousands of individual chemical species typically belonging to one of a few organic classes (e.g., n-paraffins, isoparaffins, cyclo-paraffins, olefins, aromatics). For specific combustion applications, it is often the global combustion response to variations in the composition of fuel mixtures-inclusive of those occurring by blending petroleum-derived fuel with alternative fuel candidates-that is of interest for fuel property optimization. This paper presents an overview of tools used for evaluating and emulating combustionrelevant properties of real fuels and alternative fuel candidates. New analytical and statistical methods can provide important insights as to how the ensembles of distinct molecular structures found in a given fuel mixture contribute to the physical and chemical kinetic properties that govern its combustion in energy conversion processes. Such tools can in turn assist in screening candidate alternative f...

“…Comparison of property targets for the 1 st , 2 nd , and ternary Huber-Bruno surrogate formulated to best emulate the physical properties of Jet A POSF 4658 [107]. researchers have placed primary emphasis on physical property emulation in developing surrogate fuel concepts[83,[103][104][105][106][107][108][109]. For example, Huber et al[108] have emphasized replication of the measured liquid density and viscosity of Jet-A POSF 4658, both important properties in the liquid fuel vaporization process of gas turbines.…”

This multi-university research initiative investigated "surrogate fuel" mixture methodology detailed kinetic models for representing fully prevaporized chemical kinetic/transport global combustion properties of real fuels. Concepts by which surrogate mixtures of a small number of molecular class components would emulate the global combustion properties of each specific real fuel were developed and tested experimentally by comparing surrogate mixture and real fuel behavior in a wide variety of fundamental combustion venues, including: high pressure reflected shock tube ignition delay, rapid compression machine ignition, variable pressure flow reactor reactivity/species time history, high pressure pulsed shock tube speciation, laminar premixed burning rate and strained extinction, laminar counter-flow, strained-extinction configurations, and laminar co-annular diffusive soot extinction configurations. Matching the "real fuel combustion property targets" of hydrogen/carbon molar ratio (H/C), derived cetane number (DCN), threshold sooting index (TSI), and average mean molecular weight (MW ave) of mixtures with those of the real fuel was shown to result in nearly identical global combustion behavior of the real fuel and the surrogate. Methodologies for determining combustion property targets and creating matching surrogate mixtures were demonstrated. Mixtures of surrogate components that had nearly identical combustion property targets were found to have nearly the same distribution of key (CH 2 , CH 3 , benzyl) chemical functional groups. Experimental data for surrogate components were collected from each venue, and vapor phase transport data for components and reaction intermediates were determined created. Data were utilized to test and construct detailed and reduced kinetic models for surrogate components and their mixtures. Models taken from the literature (n-decane and n-dodecane, and iso-octane) were further modified and new models were produced for toluene, n-propyl benzene, and 1,3,5 trimethyl benzene. Model reduction techniques were developed and applied to permit comparisons of predictions with flame data for burning rate and extinction. Approaches that would improve the efficiency of numerical computations were also investigated. Assimilation of physical property considerations within the context of simultaneously emulating chemical properties was also considered.
