摘要
本文以YW25G型空调硬卧列车为研究对象,采用LVEL湍流模型,模拟不同送风角度下的列车内温度场、速度场、空气龄、CO2浓度及热舒适指标PMV、PPD的分布情况,通过比较得到最佳送风角度,为改善列车室内的热舒适性提供参考依据。
The paper uses the air-conditioned hard sleeper train of YW25G type as the research object, which simulates the distribution of indoor temperature field, the velocity field, the air age, carbon dioxide concentration and thermal comfort index PMV, PPD with different air supply angles by using LVEL turbulence model. The research will get the best air supply angle and provide a reference to improve the indoor thermal comfort of train by comparing the simulation results.
