Abstract

The aim of CFD analysis is to study the flow characteristics due to the effect of offsetting in platoon of Sport Utility Vehicles (SUVs) by using OpenFOAM software. Platoons of three bodies of SUV in tandem are considered. The effect of spacing of SUV platoon on drag coefficient is assessed. The analysis of full scale SUV is performed at speed of 80 km/hr for vehicle spacing from 0.25 to 2 times length of SUV. Results show that an average drag coefficient of platoon is lower than that of standalone single SUV by 24% and consequently effect of platooning results in fuel saving. In addition, effects of offset of middle car in platoon by 10%, 20% and 30% are assessed on average drag coefficient. Offset of middle car in platoon results in an increase in average drag coefficient extended up to 6.61% as compared with inline platoon. Thus, in platooning, it will be better to maintain SUV straight-line to get full benefit of platooning.

运动型多用途车排流补偿影响下的流动特性研究

CFD分析的目的是利用OpenFOAM软件，研究运动型多用途车(suv)排流中受补偿影响的流动特性。考虑了三车身SUV的串联排。评估了SUV排距对阻力系数的影响。全尺寸SUV的分析是在车速为80公里/小时，车辆间距为SUV长度的0.25至2倍的情况下进行的。结果表明，车队的平均阻力系数比独立的单辆SUV低24%，因此车队的效果可以节省燃油。此外，还评估了排中车偏移10%、20%和30%对平均阻力系数的影响。排中车偏置导致平均阻力系数比排中车增大6.61%。因此，在队列行驶中，SUV最好保持直线行驶，以充分发挥队列行驶的效益。
