In the current research, the effects of hydrogen enrichment were studied on the thermodynamic analysis of spark ignition engines using premium gasoline-ethanol blends. The blends were prepared with a partial addition of ethanol (10 % and 20 % by volume) in premium gasoline and hydrogen was injected during combustion for 2, 3, 4, and 5 μs. The testing was done on the varying engine speeds at 1500, 2000, 2500, 3000, and 3500 rpm. Energy and exergy analyses, entropy generation, and sustainability index were assessed for different fuel blends and contrasted with premium gasoline. The brake thermal efficiency and exergy efficiency were found maximum at 2500 rpm engine speed for all tested fuel blends. The BTE of E10H5 fuel blend is 18 % higher than premium gasoline and the exhaust gas energy of the E10H5 fuel blend is 12 % higher than premium gasoline at 2500 rpm. Among all tested fuel blends, the E10H5 fuel blend showed prominent results. The present experimental investigation focuses on energy-exergy analyses of premium gasoline-ethanol blends with enriched hydrogen at different injection times to assess the potential fuel blends. These blends will help to reduce dependency on conventional fossil fuels by enriching hydrogen without modification of the engine.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"137 ","pages":"Pages 689-709"},"PeriodicalIF":8.1,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144070745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One crucial factor in its production, storage, and transportation is viscosity. However, none of the previous studies have explored the use of machine learning models to estimate the viscosity of hydrogen-based mixtures using laboratory data. To address this gap, we compiled a dataset of 1624 viscosity measurements for hydrogen-based gas mixtures from past experimental studies. Six machine learning techniques were employed for modeling: k-nearest neighbors (KNN), support vector regression (SVR), regression tree, categorical boosting (CatBoost), extra trees, and extreme gradient boosting (XGBoost). The dataset was split into 70 % for training and 30 % for testing, with a 5-fold cross-validation approach applied to validate the models during training. To assess model performance, we used cross plots, residual error plots, error metrics, and absolute error frequency plots. Among all methods, the extra trees model demonstrated the highest accuracy, achieving an R<sup>2</sup> value of 0.9983. It was followed closely by XGBoost (0.9976), CatBoost (0.9974), KNN (0.9923), regression tree (0.9917), and SVR (0.9735). Sensitivity analysis revealed that temperature had the most significant impact on viscosity, whereas methane mole fraction had the least. Additionally, at low pressures, the mole fractions of carbon dioxide and methane exhibited an inverse relationship with viscosity, while the hydrogen mole fraction showed a direct correlation. To define the applicability range of the extra trees model, a William's plot was used, indicating that 1562 data points (96 % of the dataset) were valid. Given the direct impact of viscosity on flow behavior and system efficiency, these findings can be instrumental in optimizing hydrogen production, transportation, and storage processes.</div></div>","PeriodicalId":337,"journal":{"name":"International Journal of Hydrogen Energy","volume":"138 ","pages":"Pages 331-343"},"PeriodicalIF":8.1,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144071152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
