Abstract

The transportation system is one of the most important ways for the public, commercial goods and materials to transit from one place to another place. Some of the vehicles are used such as cars, passenger buses, trucks and heavy vehicles. The drag reduction is directly effect on the fuel saving as well as the efficiency of the vehicle. Hence, for the analysis, a Computational Fluid Dynamic (CFD) analysis has been done using ANSYSR19.0 workbench and an investigation has been done. Three demo base models are considered for the analysis namely model-1 made of plastic body, model-2 made of metal body and model-3 of BD bus that run in the Bangladeshi roads. Some extensive modifications are done in the bus body such as front and rear side area which helps to reduce the aerodynamic drag of the bus. The numerical analysis for the drag forces, drag coefficient, fuel consumption and CO2 reductions have been done for model-1,2 & 3 as well as for their respective modified models. For model-3 validated with the Sunglong China bus model in the analysis. For base model-1 &2, the fuel savings 19.50% and 22.20% respectively. On the other hand, the CFD values at a velocity of 110 km/h for base model-3 the drag forces are reduced for base model modified-1, base model modified-2 as 1987.20 N, and 2499.80 N, respectively. In addition, the fuel savings for base model modified-1, base model modified-2 is 2.53 liters/hour, 4.11 liters/hour, respectively. In addition, the CO2 reductions for base model modified-1, base model modified-2 is 7.072 liters/hour, 11.488 liters/hour, respectively.
