Abstract
Aeromapping is a chart which shows the changes in a performance metric such as Coefficient of Lift, Coefficient of Drag and balance as a function of the car attitudes. A generic four-wheeler vehicle body was designed for commercial purposes. In this study, the working principle was based on Bernoulli’s principle of Fluid Flow. Laminar flow was tested on the model of the vehicle under static conditions. From the New Car Assessment Program (NCAP) standards, boundary conditions were fixed, so that the experiment can be as realistic as possible. Using ANSYS Fluent multiple simulations were done varying the experimental parameters, such as Fluid velocity, Yaw Angle of the Vehicle and varying the Fluid Pressure. All of these experiments were studied using the flow visualization, pressure graphs, graphs between independent variables etc. Successful results were achieved and the aero map was created and a significant downforce of 33% was achieved.
