摘要
利用CFD方法对汽车内部流场进行了模拟,定量分析了车内气流的速度、温度、湿度、以及车窗玻璃的温度和空气的传热量等参数,进而对汽车前风窗玻璃除霜除雾进行数值模拟,对其除霜除雾效率和效果进行分析,为汽车除霜除雾工程应用提供参考。
By using computational fluid dynamics （CFD） technique, the flow field inside the vehicle is simulated, and the velocity, temperature and humidity of internal air flow as well as the temperature of windscreen and the heat transfer between the glass and air are quantitatively analyzed. Then a numerical simulation on defrosting and defogging of vehicle windscreen is conducted with the effects and efficiency of defrosting and defogging ana- lyzed, providing references for the engineering application of vehicle defrosting and defogging.
