Experimental and Numerical Analysis of Lift and Drag Force of Sedan Car Spoiler
Nowadays, the spoiler is fitted at the rear car to make the car looks sporty without taking any consideration to its shape and aerodynamic. This paper carried out other benefits of the rear spoiler respective to the engineering point of view. These study concerns about drag and lift forces were produced by spoiler using wind tunnel test and simulation computational fluid dynamics (CFD) analysis. The main objective of this project is to compare the performances between the two methods in order to determine the aerodynamics performance of three different types of spoiler. The results of CLand CDhave been determined and compared for all the three spoilers including the baseline model as a reference. The result shows that the comparisons of all models have different value of CLand CDbut the model of spoiler 3 is more than 5%.
