空调车室内空气的速度场,温度场研究是空调车室内气流组织设计及空调室内舒适环境评价与研究的基础。针对零方程模型,k-ε湍流模型,湍流大涡模型在列车空调气流组织中的应用进行分析比较,所得结论对列车的空调效果及车内舒适环境的优化提供了依据。
The research on the velocity field and temperature field of air-conditioned indoor air is the basis of air-conditioner indoor air-flow organization design and air-conditioned indoor comfortable environment evaluation and research. The application of zero-equation model, k-ε turbulence model and large turbulence eddy current model in air-conditioners of train air-conditioners are analyzed and compared. The results provide the basis for the air-conditioning effect of train and the optimization of comfortable environment inside the vehicle.
