| Abstract: |
| Objective To obtain flow and temperature distribution in flowing heat transfer analysis of vehicle compartment. Methods A vehicle compartment was taken as the research object and the compartment was reasonably simplified. The computational fluid dynamic (CFD) model for computing air flow and heat transfer in the armored compartment was established. Air flow in the compartment was described with the standard κ-ε two-equation turbulence model. With software Fluent, simulation study on the temperature field was carried out for vehicle compartment in solar radiation. Results The relationship between distribution of temperature field and vehicle running time was obtained. The results were compared between the simulation and proving ground test, the maximum contrast error was about 12%. Conclusion With the increase of environment temperature, the temperature of vehicle compartment shows a gradient change, and the maximum temperature difference is 5 ℃ in different position inside the vehicle compartment. CFD can provide technical support for calculation and prediction of temperature field distribution. |
