Previous research has neglected the efficiency of piston wind prediction. For this reason, to improve on traditional methods, this paper uses eight different machine learning algorithms, including support vector regression (SVR), k-nearest neighbors (KNN), and extreme gradient boosting (XGBoost) et al., to construct a fast prediction model for unsteady piston winds in subway tunnels. A relatively optimal machine learning algorithm was determined through various evaluation methods, and feature importance analysis was carried out. The results show that it is feasible to utilize a machine-learning method for the fast prediction of unsteady piston winds in subway tunnels. The RF algorithm had a high prediction accuracy for unsteady piston winds, and the Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), Symmetric Mean Absolute Percentage Error (SMAPE), and Coefficient of Determination (R<sup>2</sup>) of the prediction results were 0.04, 0.05, 1.15 %, and 0.995, respectively.

It is crucial that the wind resistance (WR) in each branch of the mine ventilation network has a sufficiently small margin of error. WR is typically measured using precision barometers via a simultaneous measurement approach, or it is derived from empirical formulas based on the roadway's parameters. In practice, on-site measurements are often time-consuming and labor-intensive, and empirical formulas frequently introduce significant errors. Such errors complicate the calculation of precise airflow information, thereby impeding the accurate control of air volume. Here, we propose a WR calibrating method for roadways based on air volume. This method establishes a quadratic programming (QP) optimization model to calculate the equivalent wind resistance (EWR), utilizing actual air volume measurements and the historical wind resistance (WR) data. Moreover, the inequality constraints and weight selection of the roadway are discussed and tested. Finally, on-site verification (Ma-cheng Iron Mine in November 2023) was carried on. We find that after our method of WR calibration, the results of the ventilation network calculation were significantly more in line with the actual air distribution in the mine's roadways compared to the results without calibration. Overall, our method obtains the globally reasonable EWR and provides a reliable guarantee for air volume monitoring and regulation.</div></div>","PeriodicalId":54752,"journal":{"name":"Journal of Wind Engineering and Industrial Aerodynamics","volume":"262 ","pages":"Article 106110"},"PeriodicalIF":4.2,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843632","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}

Wind tunnel tests were conducted on panels at different tilt angles, with synchronized pressure measurements used to compute aerodynamic coefficients, spectra, correlations, and coherences for lift and overturning moment. Results demonstrate that spanwise correlations and coherences of these aerodynamics exceed those of incident turbulence for most cases.

For tilted PV panels, distinct peaks in the AAFs at elevated wavenumbers were observed, linked to shear layer instabilities in the leading-edge separation zone.
