摘要
在轿车内适当位置安装车载空气净化器可以改善轿车内的空气质量。采用标准k??湍流模型对安装车载空气净化器后所形成的气流组织分布情况进行了数值模拟分析,找到了车载净化器的最佳安装位置。数值模拟结果表明:在送风口,回风口和其它紊流强度较大的地方,其甲醛浓度会明显降低,故而适当加大紊流强度,可有助于甲醛浓度的下降;当车载空气净化器安装在驾驶席的座椅背后时,其甲醛浓度会明显比放在手套箱上面时的浓度低,因此,当车载空气净化器安装驾驶席座椅背后时,可以更有效地提高车内空气品质。
In order to improve the in-car air quality, by installing vehicle purifier to purify the air inside the car, the standard k - ε turbulence model is applied to conduct the numerical simulation analysis about the distribution of air flow organization, as vehicle purifier is placed on the different position, and through it the best position for vehicle purifier can be found. Numerical simulation results show that： in the supply air outlet, return air inlet inlet or other places that turbulence intensity is bigger, the concentration of formaldehyde will be significantly reduced, therefore moderately increased turbulence intensity can contribute to decrease the concentration of formaldehyde; when the vehicle purifier is placed behind the driver＇s seat, the formaldehyde concentration will be significantly lower compared with the situation that the vehicle purifier is placed on top of the glove box, so the vehicle purifier placed in the behind of driver＇s seat, can more effectively improve the in-car air quality.
