Abstract

Aerodynamics study on the bodywork of Formula Student Race Car executed in order to analyze the effect of drag force and lift force acting on the car’s body shape. This study focus on analyzing and redesign of the bodywork of Formula Student UTeM in term of drag and lift force reduction. The Formula Student bodywork measured using 3D-scanner and the rest of the dimension will be measured using measuring tape. Next, the model of Formula Student UTeM modeled using SolidWorks 2008 software. In order to define the effect of drag force and lift force, two method uses this is wind tunnel method and CFD techniques. Using Fluent 6.2, CFD techniques will used to determine the aerodynamics effect on the Formula Student car shape and validated using wind tunnel result. Drag coefficient and lift coefficient observed and analyze on 1:15 scale model for both method. As result, the CD based on CFD simulation differs as much as 2.28% while CL differs as much as 82.62% compared to wind tunnel. Similitude technique used in order to validate CFD result at 1:1 scale model. Three new designs proposed by modification on 1:1 model and Design 1 chosen which decreased CD as much as 0.03% and CL as much as 0.05% compared to existing Formula Student Race Car model by using CFD technique.
