La principale risposta del mondo automotive alla necessità di garantire un tipo di mobilità sostenibile nell’immediato futuro è stata la riscoperta dei veicoli elettrici.
The automotive world’s main response to the need to ensure sustainable mobility in the near future has been the rediscovery of electric vehicles. Electric mobility is seen from the outside as less polluting than that provided by vehicles with internal combustion engines; this is because, in terms of emissions, electric cars do not introduce any type of pollutant into the air. We are therefore at a time of deep development of this type of vehicles, which have already reached in performance their internal combustion engine counterpart. However, one of the main differences between the two types of vehicle is the amount of energy that can be stored inside the tank. So, in an electric vehicle, if you analyze driving on the highway (c.a. 130 km/ h), there is a sharp increase in consumption. This situation only gives the driver the perception that electric cars are more penalized by an increase in speed. The solutions to this problem can be many, for example, the development of batteries that can store more energy, increase the efficiency of the electric motors that make up the engine, or try to somehow reduce consumption. For a bluff body like a vehicle, drag is responsible for 40-60 \% of the energy provided by the powertrain. In particular, it is pressure resistance and wake resistance, a phenomenon linked to the separation of the flow. This shows that aerodynamic development with the aim of reducing vehicle drag is an area where product development is worth focusing. It is also known that there are substantial differences in terms of morphology between an electric vehicle and a vehicle equipped with an internal combustion engine: the management of internal dimensions can be addressed in totally unconventional ways, The fact that an electric vehicle ideally does not require components such as an internal combustion engine (think for example to use in-wheel motors for each tire), a transmission or a tank. The main objective of this project was to develop two geometries of ducts to reduce the total resistance of the vehicle and analyze its qualitative behavior once applied to an electric model already on the market; We then went to define and implement a procedure for aerodynamic optimization of these two ducts. The fluid dynamics analysis and optimisation process were carried out using commercial software starccm+ and ModeFrontier.
