ME7724 Assignment: CFD Analysis of a Commercial Vehicle

This report details a CFD analysis of a commercial vehicle, focusing on the determination of drag and lift forces. It explores the impact of various aerodynamic modifications on the vehicle's performance, including profile edge chamfering, windscreen rake adjustments, and the use of skirts and diffusers. The methodology involves creating a model in Solidworks, setting up a CFX simulation in ANSYS, and applying appropriate boundary conditions. The results compare the original and modified truck models, highlighting the effectiveness of different aerodynamic elements. The analysis covers key concepts like boundary layers, skin friction, and the influence of air streamlines, providing a comprehensive understanding of vehicle aerodynamics and the application of CFD in mechanical engineering. The report also includes a discussion of the results, a conclusion, and recommendations for further improvements.
