- W3203348304 abstract "Aerodynamic design of an automotive vehicle influences the performance,safety,and maneuverability of the vehicle.The factor of rising price of the fuel besides the world vision on reducing the greenhouse effect are some of the aspects that boost the needs of refining the vehicle aerodynamics.There is a fact that the design of the vehicle affects 11% of fuel to overcome the drag force on a high-speed driving.Furthermore,the shape of the vehicle especially sedan type has greatly affected by the lift force.Undesirable high value of lift force on an automotive vehicle could cause lack of stability and safety.In this study,the improvisation of the aerodynamic characteristics of a vehicle is discussed in term of rear- wing spoiler design.Four spoiler designs are proposed,analyzed and compared to each other.The drag and lift coefficient value of the vehicle with attached spoiler,the pressure and velocity distribution are evaluated in determining the best spoiler design.The flow characteristics were analyzed using ANSYS FLUENT®.The CFD technique used is validated by using the Ahmed body as a benchmark as the experimental result on themodel is available.Grid independence study is conducted in determining best mesh resolution and turbulence model for this study.The generic sedan car as a base model and the spoilers are created in CATIA®.The base model is attached with various spoiler designs and tested to gather its data and result.The finding of the study shows that without a spoiler,the drag and lift coefficient of the car are 0.19230 and 0.03957.While when attached with spoiler,there is an increment in the drag coefficient of the car in range of 26.68% to 150.89%.However,the lift coefficient value shows a declination in range of 1.39% to 1992.87%.The best spoiler design is spoiler 3.The best spoiler design should have the least drag coefficient increment and considerably higher negative lift coefficient." @default.
