A4 - Zineddin, Abdul A4 - Durbin, Dennis; Zineddin, Abdul AB - Under the SAFETEA-LU Congressional Bill, the Secretary of Transportation was directed to conduct a national wildlife-vehicle collision (WVC) reduction study. The study was to advance the understanding of the causes and impacts of WVCs and identify solutions to this growing safety problem. This report contains the findings of this study, beginning with estimates on the current magnitude and trend for WVCs in the United States. Based on several national datasets, the study found that there are between one and two million WVCs annually in the United States and that the number is increasing. Estimates are provided for the costs associated with WVCs, and the impact of direct road mortality is described for 21 federally listed threatened and endangered species. The core of the report is an in-depth review of over 34 WVC mitigation methods assembled from information obtained from hundreds of literature sources (both published and “gray” literature). Each mitigation measure is described in detail, and information including case studies, benefits, costs, undesirable effects, and design guidelines is provided. The report also covers planning and design considerations and provides cost-benefit analyses for the mitigation methods that had sufficient data available to support these analyses. A working group of seven national experts provided input and evaluated the effectiveness of the mitigation methods, categorizing them as either recommended for implementation, recommended for future research, or not recommended for future research or implementation. A summary of their evaluation is included in this report. Recommendations for implementation of effective measures and for further investigation of promising mitigation measures are provided.

Office of Environment and Energy AB - This study investigates the ignition behavior of six dimethylcyclohexane (DMCH) isomers and cis-/trans-decalin, focusing on the effects of molecular geometry and substitution patterns. Ignition delay and derived cetane number (DCN) were measured using a CFR ignition quality tester under ASTM D6890 conditions. Among the DMCH isomers, cis-1,3-DMCH exhibited the highest reactivity (DCN = 37.4), while cis-1,2-DMCH showed the lowest (DCN = 21.8). The most significant stereochemical effect was observed between cis- and trans-1,3-DMCH, with a 12-unit DCN difference. Temperature- and pressure-dependent tests of decalin isomers revealed that cis-decalin consistently ignited faster and exhibited stronger pressure sensitivity, supporting a mechanistic interpretation based on 1,5- versus 1,6-H shift pathways. Additionally, the impact of trace polar degradation products on ignition delay (ID) was assessed, revealing significant ID reduction in trans isomers after storage. These findings highlight the need to consider geometric isomerism in kinetic modeling, sustainable aviation fuel formulation, and surrogate design, particularly for fuels rich in cycloalkanes.

Now, there is no certified conversion process of food waste for SAF by American Society for Testing and Materials (ASTM). We report the use of zeolite-supported molybdenum carbide nanocatalysts in upgrading biocrudes, produced from food wastes through HTL, into SAF precursors. Our data show a complete removal of oxygen from the biocrude through hydrodeoxygenation and a higher heating value of 46.5 MJ/kg, which is comparable to that of Jet A (46.1 MJ/kg). The prescreening tests (tier alpha and beta) show the average carbon number of the distillation cut (150° to 230°C) of upgraded fuel is 10.6, close to the value of 11.4 for average conventional jet fuel, and the specifications of properties including surface tension, viscosity, heating value, flash point, and freezing point were found to meet the standards of SAF. The metal carbide nanocatalysts were reusable in upgrading tests, and the activity of deoxygenation was retained.

Office of Environment and Energy AB - The ability to predict the vapor pressure and vapor-phase composition of hydrocarbon mixtures (such as jet fuel, sustainable aviation fuel or its un-refined precursors) and partially vaporized hydrocarbon mixtures is important to simulations of processes that involve vaporization such as distillations, flash points, combustion properties of partially vaporized fuels, etc. Raoult’s Law provides a simple algebraic formula relating liquid composition and temperature to vapor composition and pressure. However, Raoult’s Law is not accurate at low mole fractions, which is typical for complex mixtures such as fuels. A common approach to correcting Raoult’s Law is to apply a scale factor, a so-called activity coefficient. Numerous models exist for predicting activity coefficients. Here we benchmark against the UNIFAC model, which predicts activity coefficients based on mole fractions, group fractions, Van derWaals volume and surface area and temperature-dependent interaction terms between groups. While this approach is truly predictive, its accuracy at very low mole fractions has not been validated, and it is computationally intensive, particularly for simulations (especially optimizations) that require vapor composition or pressure within the inner-most loop. Here we present an alternative correction to Raoult’s law, where the vapor pressure of the ith component is represented by a modified form of the Clausius–Clapeyron equation.

Federal Aviation Administration. Office of Environment and Energy AB - Experiments using pure compounds, National Jet Fuels Combustion Program (NJFCP) test fuels, and commercial jet fuels were conducted to demonstrate the equivalence of the indicated cetane number (ICN) and derived cetane number (DCN) for jet fuels. The calibrated range for ICN was also extended to lower cetane number (CN) values (5 to 35) to allow CN quantification for jet fuel synthetic blending components (SBCs) with low CN. ICN and DCN were shown to be highly correlated for values above about 30. This study presents the most comprehensive comparison of these two methods published to date. Because of the importance of low-volume test methods for early-stage SBC production process development, we demonstrated that ICN and DCN can be accurately measured with 15 mL of fuel, well below 40 to 100 mL required by standard methods. ICN or DCN is important for jet fuels because fuels with lower CN are more prone to lean blowout (LBO), an undesirable operational failure in a jet engine. Comparing data on a fuel-to-air ratio (Φ) at LBO for the NJFCP fuels shows similar linear correlations for ICN and DCN. Ignition delay measurements at lower-pressure and higher-temperature conditions may be more directly relevant to LBO. At 675 °C, 0.5 MPa, and a global Φ of roughly 0.68, ignition delay time correlations to LBO were similar to those produced from DCN and ICN.

Office of Environment and Energy AB - A comprehensive uncertainty quantification (UQ) of soot volume fraction (SVF) predictions in the primary zone of a Rich-Quench-Lean (RQL) combustor is presented, with particular emphasis on the modeling uncertainties in the rates of nucleation, growth, oxidation, condensation, and coagulation. Large-eddy simulations (LES) of soot formation in a realistic single-sector RQL combustor are first performed, and the local thermochemical data, along with the volumes of the zones containing the respective finite volume cells, are then used to construct a chemical reactor network (CRN) model. The CRN model, coupled with the UQ tool DAKOTA, is used to conduct forward UQ, sensitivity analysis, and inverse UQ. The forward UQ indicates variability ranging from 28 % to 89% around the mean soot prediction, depending on the location within the combustor. The local and global sensitivity analyses highlight the contributions of nucleation and condensation processes near the fuel injection zone, while growth and oxidation processes predominantly influence soot predictions in the primary zone. Since the baseline model underpredicts soot compared to experimental measurements, a Bayesian inference-based inverse UQ analysis is performed to identify sensitive input rate uncertainties that can improve the quantitative agreement with experimental soot levels. Thus, the overall strategy identifies the most influential aspects of the soot model, their relevant sensitivity to local zones within the combustor, and further refinements to the baseline rates that can provide valuable insights for future model developments.

Office of Environment and Energy AB - Multirotor electric vertical take-off and landing vehicles and small unmanned aircraft systems commonly use distributed electric propulsion. One approach to reducing their noise involves synchronizing rotor phase relationships to control radiated noise directionally. This paper presents a practical electronic phase synchronization method for multirotor aircraft, experimentally evaluates its effectiveness using a hexacopter in an anechoic chamber, and investigates how vehicle configuration influences noise control capability. Harmonic noise reductions of 10 dB are demonstrated over a 20◦ azimuthal arc, with limited increases in other directions. Noise amplification of 6 dB is also achieved over the same region. Global reductions of 6 dB across nearly all observer angles are obtained using alternative rotor phase offsets. Statistical analysis of phase controller error indicates that maintaining phase accuracy within 5◦ is necessary for 10 dB attenuation. Simulations across various rotor configurations show consistent noise control performance, with higher rotor counts enabling greater directional control of radiated noise.
