Progress in combustion science and engineering has led to the generation of large amounts data from large-scale simulations, high-resolution experiments, sensors. This corpus offers enormous opportunities for extracting new knowledge insights—if harnessed effectively. Machine learning (ML) techniques have demonstrated remarkable success analytics, thus offering a paradigm data-intense analyses scientific investigations through machine (CombML). While data-driven methods are utilized various...
A model for the prediction of nitric oxide (NO) formation in turbulent nonpremixed flames is proposed. Since NO has a strong temperature sensitivity, accurate flame under consideration radiative heat losses required. The first part paper addresses extension flamelet-based combustion to account loss effects by introducing enthalpy as an additional parameter. transport equation solved, and sink term this obtained from unsteady flamelet solutions. applied large-eddy simulation (LES) Sandia D,...
The implementation of advanced low-emission aircraft engine technologies and the reduction noise from airframe, fan, jet exhaust have made contributions an core increasingly important. Therefore, meeting future ambitious noise-reduction goals requires consideration engine-core noise. This article reviews progress on fundamental understanding, experimental analysis, modeling noise; addresses limitations current techniques; identifies opportunities for research. After identifying core-noise...
Abstract Recent experiments on pure fluids have identified distinct liquid-like and gas-like regimes even under supercritical conditions. The liquid-gas transition is marked by maxima in response functions that define a line emanating from the critical point, referred to as Widom line. However, structure of analogous state transitions mixtures has not been determined, it clear whether can be for binary mixtures. Here, we present first evidence existence multiple lines molecular dynamics...
Abstract A major barrier toward the practical application of lithium-oxygen batteries is high overpotential caused by precipitation oxygen-reduction products at cathode, resulting in poor cyclability. By combining first-principle calculations and reactive molecular dynamics simulations, we show that surface functionalization 2D MXene nanosheets offers a degree tunability catalytic activity for oxygen-evolution reactions (ORR/OER). We controlled creation active vacancy sites on enhances ORR...
Predicting wildfire spread is critical for land management and disaster preparedness.To this end, we present 'Next Day Wildfire Spread,' a curated, large-scale, multivariate data set of historical wildfires aggregating nearly decade remotesensing across the United States.In contrast to existing fire sets based on Earth observation satellites, our combines 2D with multiple explanatory variables (e.g., topography, vegetation, weather, drought index, population density) aligned over regions,...
Abstract Supercritical fluids play a key role in environmental, geological, and celestial processes, are of great importance to many scientific engineering applications. They exhibit strong variations thermodynamic response functions, which has been hypothesized stem from the microstructural behavior. However, direct connection between conditions behavior, as described by molecular clusters, remains an outstanding issue. By utilizing first-principles-based criterion self-similarity analysis,...
A new engine model has been developed for applications requiring run times shorter than a few seconds, such as design optimization or control evaluation.A reduced-order mixing and combustion that is based on nondimensional scaling of turbulent jets in crossflow tabulated presumed probability distribution function flamelet chemistry.The three-dimensional information from these models then integrated across cross-sectional planes so one-dimensional profile the reaction rate each species can be...
