Analysis shows temperature variation in railway freight containers due to solar radiation, indicating important implications for dangerous goods transport.
Based on the development of railway dangerous goods transportation under the Belt and Road Initiative, this study focuses on the impact of solar radiation on containers and the internal cargo temperature in the western plateau regions. A physical model of a 20-foot universal container was developed. Utilizing SolidWorks and ANSYS for modeling and meshing, a mathematical model incorporating heat conduction, convection, and thermal radiation was constructed. By introducing a solar load model and the S2S (surface-to-surface) radiation method, the temperature variation process under typical daytime conditions in Lanzhou City was simulated.
