“…We calculated the flame pulsation frequency in Fig. 2, based on the Fast Fourier Transformation (FFT) method [25][26][27]. It shows that the flame pulsation frequency decreases with the increase of ullage height for 15-cm pool fires, and a similar trend was also found for 10-cm pool fires with flame pulsation frequency decreasing from 5.26 Hz (h/D=0) to 2.83 Hz (h/D=1.4).…”

“…And those images recorded during the steady burning stage were used to validate the numerical model. Ostu method was applied to processing these images to obtain the statistical data of the flame characteristics, which was proved to be a reliable method [37][38][39]. An electronic balance with a precision of 0.1 g was adopted to record the fuel consumption rate.…”

“…During a visit to a mining enterprise in Shanxi Province, a scaled-down model of a roadway section measuring 4 m × 5 m was established. The model was created based on the principles of power similarity and motion similarity in hydrodynamics, ensuring that it was isometrically scaled with the actual model [22][23][24] (pp. 179).…”

To investigate resistance change in the fire area of a roadway caused by roadway fires, a mathematical calculation model for thermal resistance is developed. Theoretical research is conducted to analyze the factors influencing resistance change through theoretical derivation, revealing that temperature is a key factor contributing to the change in thermal resistance. By leveraging the correlation between changes in CO concentration and temperature on the downwind side of the roadway within the fire zone, researchers developed mathematical models to predict temperature increases at various points downwind of the fire source. These models were then used to determine the mathematical relationship governing the change in thermal resistance. The accuracy of the numerical simulation software was validated using Fluent numerical simulation software and scaled-down model experiments. Full-scale numerical simulation experiments were conducted to investigate the fire characteristics of roadway fires and validate the thermal resistance mathematical model. The results indicate that the thermal resistance in the numerical simulation is 7.55 Pa at 20m from the fire source and 5.54 Pa at the end of the roadway. The decrease in resistance is linear. The minimum error between the thermal resistance calculated by the mathematical model and the gradient of the pressure drop in the numerical simulation is 0.03 Pa, approximately 2.3%. Furthermore, the fitting degree of the pressure drop in each section is as high as 97.7%. The calculation model demonstrates high accuracy and offers a theoretical foundation for investigating fire resistance in tunnel fire.
