A car with a good aerodynamic design works efficiently. The sidepod is one such aerodynamic device that aids in increasing the cooling performance of a radiator. The objective of this article is to validate the design of the sidepod, which provides the maximum possible mass flow rate of air, which in turn increases the efficiency of the radiator. Validation was performed by comparing the values of mass flow rate obtained by analytical calculations, simulations, and experimentation. Firstly, analytical calculations were performed on the sidepod using the principles of fluid dynamics. Six models of the sidepod were designed with varying dimensions with undertray and without undertray. Simulations were performed on the models to find the design of the sidepods that provide results closest to the manually obtained values. An attempt was made to describe the setup required for simulating these sidepods along with the radiator, fan, and shroud.

The FSAE is a world-renowned competition, in which students from across the globe compete against each other. The chassis is the main framework of the car, which is inherently responsible for accommodating all the components. The chassis is broadly classified into two types—monocoque and spaceframe. The FSAE chassis is of spaceframe type. The chassis also provides structural rigidity to the body of the car. It was observed through literature study that very minimal amount of research has been done on analyzing and validating the chassis by applying the different meshing techniques, namely 1D, 2D, and 3D. The mesh quality is very essential to obtain precise results and hence, effective methods for creating the mesh have been dealt with in this article. This study is on new investigations on different meshing techniques that can be implemented on an FSAE chassis.
