摘要
运用FLUENT模拟汽车空调开启降温过程中的6组不同送风参数(送风温度、送风速度)对车内速度场和温度场的影响。计算采用SIMPLE算法,三维湍流采用RNG模型,空调入风口采用速度入口,出口采用压力出口。计算结果表明:在进风温度不变的情况下,随着进风速度和进气量的增加,车内空气流动越剧烈,车内平均速度越高,车内平均温度也随之降低;在进风速度不变的情况下,随着进风温度的增加,车内空气流动平均速度基本相近,而车内平均温度则逐渐升高。
The influences of the six groups of different air parameters（temperature of supply air, velocity of supply air） on the interior velocity and temperature field during the process of opening the cooling function for the vehicle air conditioning is simulated using FLUENT. SIMPLE algorithm is used for calculating, RNGmodel for three-dimensional turbulence, velocity inlet for air inlet, pressure outlet for outlet. The results show that： with the increasing of speed and amount of intake air, the interior air flows more intensely, the higher average speed of the automotive interior, the lower average temperature of the automotive interior when the inlet air temperature remains unchanged; With the increasing of inlet air temperature, the interior airflow average rate is substantially similar and the interior average temperature is gradually increased when speed of inlet air remains unchanged.
