Quality Determination of Aerodynamic Analysis in Vehicle by Using CFD

An operating Deluxe bus was benchmarked and analyzed for styling, aerodynamic performance and comfort. Fluent, a commercial CFD code was used to evaluate the aerodynamic performance. Principles of product design were used to analyze the styling and comfort.The exterior styling, drag force reduction and aerodynamically efficient design for reduced fuel consumption are the three essential factors for a successful operation in the competitive world. The bus body building companies prioritizes the exterior looks of the bus and ignores the aerodynamic aspect. Scientific design of sleepers for increased comfort of the passengers is seldom seen. The overall aim of this project was to redesign a Volvo bus with enhanced exterior styling, reduced aerodynamic drag and increased comfort for the passengers.The Two prototype bus body has been modeled by using CFD to reduce the drag force. These are namely model 1 and model 2. Model 1 is existing Volvo intercity bus model and model 2 is modification of existing Volvo intercity bus. Model 2 is to modify and analyze by using CFD to reduce the drag force
