This work presents spatially- and temporally-resolved experimental and computational results for gas-phase emissions from a utility-pipe flare (7.62 cm diameter) under varying crosswind speeds. Emissions measurements are presented for high and low combustion efficiency (CE) using natural gas and a propane and natural gas blend. The experiments considered flow rates of 98 liters per minute (LPM) for natural gas with crosswind speeds of 0.3 m/s (CE = 100 % ± 0.03 %) and 10 m/s (CE = 80.2 % ± 2.46 %). The propane and natural gas blend experiments were conducted at a flow rate of 490 LPM and crosswind speeds of 8.8 m/s (CE = 94.3 % ± 2.71 %) and 16 m/s (CE = 88.0 % ± 2.71 %). Large-eddy simulations (LES) of methane at 830 LPM with crosswind speeds of 3 to 12 m/s yielded CE values from 99.45 % to 95.89 %. Both experiments and LES demonstrate that severe thermal and species gradients persist well downstream of the primary combustion zone. LES further reveals that local CE can deviate significantly from global CE, underscoring potential limitations of emissions measurement approaches. The findings provide a benchmark data set for flare emissions under crosswind conditions and highlight the need to refine existing analytical methods while guiding the development of next-generation measurement strategies.</div></div>","PeriodicalId":100104,"journal":{"name":"Applications in Energy and Combustion Science","volume":"25 ","pages":"Article 100448"},"PeriodicalIF":5.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145925452","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Decking materials may be particularly vulnerable to ignition from firebrand piles. However, large-scale studies replicating real-world conditions are still lacking. This study investigates the observed thermal response of Pressure Treated Wood (PTW) and Trex Enhance (Trex) composite decking under exposure to 8 grams firebrand piles (10 cm × 5 cm x 2 cm) at large-scale decking assembly (60 cm × 60 cm). Experimental conditions involved different constant wind speed (1.4 m s^-1 and 2.7 m s^-1); moisture content (MC) of tested materials (PTW: 26% and 7%; Trex: &lt;1%); and firebrand pile orientation (0°: 10 cm side parallel to airflow; and 90°: 10 cm side perpendicular to airflow). For PTW experiments, three key events were observed: 1) Burn-through: when the samples experienced vertical propagation until a glowing-edged opening &gt;5 mm appeared at the back surface; 2) Back surface flaming ignition: when transition from smouldering to intense flaming ignition took place at the back surface; and 3) Back surface re-ignition: when flaming ignition appeared second time at the back surface but at lower intensity. For PTW, the higher wind speed (2.7 m s^-1) was the dominant factor associated with significantly increased likelihood of burn-through and was a necessary factor in inducing back surface flaming. The low MC (7%) also increased the propensity for burn-through and back surface flaming, though to a lesser extent. Although firebrand pile orientation showed insignificant impact on the overall thermal response, it still played a critical role. The 90° orientation increased the burn-through propensity, while 0° orientation displayed a greater tendency for back surface flaming and its associated characteristics. Compared to PTW, Trex exhibited considerably lower combustion intensity and duration, with no observations of burn-through or back surface flaming in any experiment.</div></div>","PeriodicalId":100104,"journal":{"name":"Applications in Energy and Combustion Science","volume":"25 ","pages":"Article 100463"},"PeriodicalIF":5.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146022803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this, we propose and validate dry ice as a highly efficient LIB fire suppressant. First, a study on dry ice’s efficacy in inhibiting thermal runaway propagation (TRP) in 4000 mAh cylindrical LIBs demonstrates optimal suppression during early-stage fire development, with efficacy positively correlated with discharge quantity. Further validation on a 50 Ah energy storage cell confirms that dry ice extinguishes open flames within 3 seconds while significantly reducing surface temperature, effectively halting TR progression. Finally, the fire-extinguishing mechanism of dry ice was summarized, i.e., gas-driven accelerated phase transition - rapid fire extinction by low-temperature gas cloud - sustained cooling via thermal resistance barrier. This multi-phase mechanism rapidly blocks TR propagation chains. Collectively, this work provides an efficient and feasible fire-suppression strategy to mitigate the major process safety risk posed by LIB thermal runaway (TR).</div></div>","PeriodicalId":100104,"journal":{"name":"Applications in Energy and Combustion Science","volume":"25 ","pages":"Article 100437"},"PeriodicalIF":5.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145790913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method was applied to methane and natural gas combustion, targeting key combustion properties: ignition delay times (IDT) and laminar burning velocities (LBV). The approach combines a detailed H₂/CO core with virtual reactions representing the main fuel oxidation pathways through fuel, fuel radical, and aldehyde virtual species. For natural gas, fuel components were lumped, and averaged thermodynamic properties were assigned to the virtual species. The optimization process produced simplified models with 14 species and 57 reactions, which could accurately reproduce the IDT and LBV simulation results of the AramcoMech 3.0 detailed model across a wide range of equivalence ratios and temperatures. The mean absolute deviations for all test conditions were 11.9% for IDT and 2.5% for LBV in methane, and 10.5% for IDT and 1.4% for LBV in natural gas simulations. The models could capture the tendency differences between methane/air and natural gas/air mixtures in ignition characteristics while preserving the similarities in flame propagation.

Characterization techniques together with quantum chemistry calculations are carried out to investigate the mechanisms behind the red-shifted fluorescence. It was found that a room-temperature HNO₃ wash can significantly red-shift the fluorescence of flame-formed carbon dots from ∼535 nm to ∼620 nm and cause a shorter fluorescence lifetime. The particle diameter and in-plane correlation length of the aromatic lands were not significantly changed, but the N-containing species were detected after the HNO₃ wash. Further spectroscopic analysis showed that the responsible nitrogen species for the red-shifted fluorescence was –NO₂, which possibly stemmed from the C=C reactive sites on the flame-formed carbon dots, as the C=C content decreased while the –NO₂ content increased after the HNO₃ wash. The excited state analysis shows that –NO₂ functional groups can lower the HOMO-LUMO gap of the flame-formed carbon dots and red-shift the 1π→π* transition. The hole-electron analysis shows that the excitation of the unmodified model is the local excitation within the π-conjugated domain, while that of the N-modified model is the charge transfer excitation from the π-conjugated domain to the peripheral –NO₂ functional groups, which can lead to the non-radiative decay and low quantum yield.

With the popularity of monitors, battery management has become an increasingly important indicator for evaluating the effectiveness of monitor usage. The Remaining Useful Life (RUL) of a lithium battery is an important parameter that characterizes the functionality of a battery management system. Accurate prediction of the RUL of a lithium battery can ensure the smooth operation of the battery equipment and guarantee the utilization efficiency of the monitor. In response to the problem of low estimation accuracy caused by complex estimation models in current lithium battery RUL prediction, a lithium battery RUL prediction method using Variational Mode Decomposition (VMD) and Relevance Vector Machine (RVM) is proposed by selecting the time when the discharge phase voltage drops to the cut-off voltage as the health indicator. Firstly, the time when the voltage drops to the cut-off voltage during the discharge stage is used as a health indicator, and Spearman correlation analysis is used to determine that the voltage drop time has a strong correlation with the battery's capacity data. Secondly, due to the phenomenon of capacity regeneration in battery capacity, VMD is used to decompose the voltage drop time signal, and RVM is used for training. Finally, the voltage drop time data is input into the VMD-RVM model to obtain the predicted RUL of the battery. Verified using NASA's publicly available dataset, the experimental results show that the VMD-RVM prediction method used in this paper has lower MAE and RMSE compared to EEMD-RVM and EMD-RVM, indicating that the proposed method has higher accuracy.</div></div>","PeriodicalId":100104,"journal":{"name":"Applications in Energy and Combustion Science","volume":"25 ","pages":"Article 100432"},"PeriodicalIF":5.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145651983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
