摘要
以京沪高速铁路某列车检修库为例,利用CFD技术,对检修库联合供暖设计方案中列车底部热风系统的实施效果进行了模拟。结合8个典型算例,对检修库内空气速度分布、温度分布、热舒适度指标PMV分布及列车表面的热流密度进行了模拟,确定了合理的送风口位置和最佳的送风参数。
Takes the train service shop of high speed railway between Beijing and Shanghai as an example, adopts CFD methods to simulate the effects of hot air system which is a part of combined heating system and located under the train. Based on eight typical cases, simulates the air velocity distribution, air temperature distribution, PMV distribution and heat flux density through the train surface, and finds proper locations of air supply inlet and optimal air supply parameters.
