Enhancement of Aerodynamic Efficiency of Truck-Trailer

Pradeep Kumar, Nidhi Chaurasia

The CFD (Computational Fluid Dynamics) analysis is the well known analysis which is done to parameters of the interface between the body and the fluid. Fluid flow around the body is major topic of concern so the CFD is held. These analyses will helping in minimize the fuel consumption of a freight vehicle, Truck-trailer and increase its stability while at work. One parameter on which the whole project depends is the Drag coefficient of the body which is being determined in the project further. The analysis is done in ANSYS software and Coefficient of Drag is obtained. A truck-trailer as a ground vehicle is considered. The project will be dealing with the air flow around the body at high speed of 30 m/s. Analysis will be done by considering the Menter’s SST (Shear Stress Transition) model as standard. Simulation would be done on different cases with some improvements on the body and comparing them. Velocity contours and vector fields will be obtained along with the Coefficient of drag. A single modified device or body is analyzed at a time and there COD are to be noted for improvements.
