摘要
本文以铁路空调客车为研究对象,采用k-ε双方程模型,对客车室内的气流组织进行数值模拟,得到了有车内热负荷存在时的车内温度、速度场分布模拟计算结果。通过与试验结果的对比,对影响车内温度、速度场的因素进行了初步分析。
Taking the air - conditioned railway passenger car as subject investigated and using the k - ε double - equation model,this thesis makes the numerical simulation of airflow organizing inside the car.The sumulated calculation results of air temperature field and air velocity field distribution inside the car were obtained with the condition that there was heat load inside it. By comparing the results with those of test, the preliminary analysis of factors that influence the temperature field and velocity field in the car was made.
