“…Extensive amount of research has been carried out in the field of airflow characteristics through an FSAE car sidepod and also approaches used for performing CFD analysis in similar cases. Wang et al, [1] analyzed the effect of rear mounted radiator and concluded that the rear mounted radiator can result in a 4% improvement in standard lap time. Bahuguna et al, [2] used both theoretical and simulation models to calculate the heat transfer coefficient and temperature drop through the radiator with varying parameters like core size, mass flow rate of water and air, fan configurations.…”

In Formula Society of Automotive Engineers (FSAE) cars engine heat management serves as an important factor for the performance of the vehicle. Therefore, a proper design of sidepod is crucial for optimal cooling of the engine since sidepods are designed to direct the airflow through the radiator. Also, since sidepods play an important role in the aerodynamic performance of the vehicle, factors such as drag and lift must also be considered along with the cooling of the engine. This paper brings forth the methodology carried out to design the sidepods effectively. First the optimal radiator angle is determined on which the maximum mass flow rate of air through the radiator core is observed. Angles are varied from 50, 70 and 90 degrees on various orientations with respect to the car. Fixing this radiator angle, various inlet and outlet areas of the sidepod are analyzed. Choosing the model with least drag and lift coefficient the sidepod is analyzed by sealing it at various sides. Finally, the effects of gills are also analyzed for better optimization of the sidepod. The models are designed in Solidworks and the CFD simulations are carried out in Simscale. Half car simulation is performed with symmetry conditions in order to reduce the cell count. The results of the analysis showed that the radiator angled forward with a diverging type sidepod yields in the better cooling of the engine.

<div class="section abstract"><div class="htmlview paragraph">Heat transfer optimization is a crucial aspect of the design process for Formula Student race cars, particularly for the radiator, usually housed in a side pod. For the car to operate at peak performance, a well-designed radiator-sidepod system is essential such that it can dissipate heat generated by the engine faster, for the car to run in optimal performance. Testing the car physically for various radiator-sidepod design iterations is a very difficult task, also considering the costs to manufacture the radiator-sidepod setup. The objective of this study is to develop a comprehensive methodology for analysing heat transfer through radiator setup using Computational Fluid Dynamics and to validate it through experimental investigations, to enhance performance and efficiency of the radiator setup. It further explains how to find out its heat transfer efficiency, and to choose the right radiator-sidepod setup, giving optimal performance. The flow of coolant inside the radiator, as well as external air flow through sidepod, is considered for realistic results in numerical analysis. Various radiator dimensions and sidepod designs are considered in the scope of this paper. The heat transfer simulation is performed in ANSYS Fluent, and their results compared. The final radiator-sidepod setup concluded as optimal setup in this study provided an average temperature drop of 2.9 °C through experiment and 2.72 °C through numerical analysis, providing uniform airflow through the radiator face with less dirty air.</div></div>
