Numerical Study of The Effects of Vehicle Arrangement on Aerodynamics Resistance

The cause of drag force vehicle accounts high fuel losses. Fuel consumption is adversely affected due to aerodynamic forces, which specially the force. Vehicles that are moving in certain arrangement allows for a significant decrease at highway speeds by reducing on vehicles. In this paper, effect resistance was numerically investigated. models were arranged back-to-back with difference distances between each other. distance varied 1.5 m, 2.0 m and 2.5 m. Computational Fluid Dynamics (CFD) performed using ANSYS-Fluent software. results terms coefficient obtained setting. There nine different arrangements studied. It found out lowest average 0.1857 experienced model 1.5m This shows reduction 26.8%. Consequently, aerodynamics can be significantly reduced having proper cruising highways.
