“…The idea of a transportation system using evacuated tubes has several benefits, including low energy consumption, increased speed, lower noise pollution, lower aerodynamic resistance, etc. [8][9][10]. Zhang et al, [11] outlined a few important problems with evacuated tube transportation systems that need to be taken into account during the design phase.…”

Aerodynamic drag is one of the most opposing factors for ground vehicle. This becomes even more difficult while travelling through a tunnel. The Evacuated- Tube Trains (ETTs) or Hyperloop’s are a new concept of ground transportation presently being developed by many different companies. The main purpose of an Hyperloop can be displayed as a cheaper medium of ground transport, which could allow its consumers to propagate to different places at a cheaper and faster rate compared to the present day locomotives and road transport. Passengers can travel at over 700 mph in floating capsules that swoop along within gigantic low-pressure tubes that are either below or above surface. This study analyses the Hyperloop designs using Computational Fluid Dynamics software ANSYS FLUENT. The effects of operating speed, Capsule shape and internal tube pressure have been studied in this paper. The flow inside the tube is considered as turbulent and incompressible. The software simulation results show the significant effects of inside pressure and operating speed on the aerodynamic drag of the capsule. Study with different shapes for the Capsule’s front and rear end suggest the most optimum shape for least aerodynamic drag.

“…Kamath et al, [5] studied the effect of radiator angle and radiator seal using CFD and concluded that an angled radiator without a seal yields higher mass flow rate of air through the radiator. Srivastava et al, [6] optimized a diverging-converging type sidepod using internal CFD simulations and concluded that a small inlet area results in increased mass flow rate of air through the radiator. Harish and Venkatasubbaiah [7] and Waman and Harish [8] worked on developing a complete aerodynamic package for an FSAE car and had also validated their results with experimental setups.…”

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.
