Abstract – The increase in energy consumption may accelerate studies focusing on increasing the efficiency of current energy sources and utilization of renewable energy sources. For transportation, renewable energy sources are getting more important because of strictly regulated emission values and vehicle noise restrictions in urban areas for quality of life requirements. Researches in electrical transformation, energy storage, weight reduction and aerodynamical improvements are getting popular with increasing number of electric vehicles. In this study, the aerodynamic effects of composite (Polymer Composites Plate) wheel cover of the EV Demobil 09 produced by Solaris Team of Dokuz Eylül University is analyzed. Composite wheel covers were produced by vacuum assisted resin transfer molding (VARTM) methods. To improve the aerodynamic characteristics, the flow around the vehicle were examined via CFD (Computational Fluid Dynamics) methods.
