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.
