确定空调车室内流场和温度场的分布和变化过程是其气流组织设计及车室内舒适环境评价与研究的基础。空调车室的流场、温度场数值计算是包含复杂流动边界、复杂热边界的数值计算问题。文中介绍了空调车室内空气流动的数学模型及复杂边界条件的处理,讨论了瞬态温度场模拟的几个问题。通过Fluent软件完成空调车室内的瞬态温度场的模拟分析,得到了合理的车室气流组织情况和温度分布结果。
Determining the distribution and changing process of flow field and temperature field in air conditioners is the basis of the air flow organization design and the evaluation and research of indoor comfort environment. The flow field and temperature field of air-conditioned cab are numerical computational problems that involve complex flow boundaries and complex thermal boundaries. The article introduces the mathematical model of air flow in air conditioners and the treatment of complicated boundary conditions. Several problems of transient temperature field simulation are discussed. Fluent software was used to simulate the transient temperature field in the air-conditioned cabin and a reasonable airflow distribution and temperature distribution were obtained.
