摘要
为深入研究DF8CJ型机车通风机和风道的流场情况和匹配关系,改进既有的通风机研制方法,提高通风机的效率,提出了采用FLUNET软件进行流场分析和研究的方法。对改进方案进行了数值分析。通过比较,减小安装角的改进方案效率提高得较多。
In order to study the flow field and the matching relation of ventilator and flow field, improve the developing method of current ventilator and improve the ventilator efficiency, this paper put forward to study the flow field by adopting FLUENT software. The modified scheme has been analyzed by numerical analyze method. By comparing, the scheme by reducing installation angle can highly improve efficiency.
