Abstracts: Recently aerodynamics behaviours of heavy commercial vehicles have been studied for understanding drag reduction and it’s directly influences on fuel consumption for heavy vehicles. Behaviour of fluid flow over an auto mobile vehicle can understand by using numerical technique available in CFD tools. In this study, numerical solution has been carried out for two dimensional turbulent flow around heavy vehicle body. Simulation has been carried out for the same configuration without roof spoiler at different range of speed to estimate value of drag force. Results obtain from CFD tools shows the drag force at different speed with different shape of vehicle.
