Abstract : Energy efficiency of a road vehicle is highly attributed to its aerodynamic performance. Over some past decades, several improvement has been made and reduced significantly the aerodynamic drag; but, beyond the current achievement, improvement become difficult and challenging for car industry and professionals working in the area. In this regard, this paper focuses on new approach to further find aerodynamic performance improvement particularly for electric vehicles. Therefore, a preliminary numerical study on ducting and concept of energy harvesting from aerodynamic resistance is introduced in this paper. In this numerical study, ducted and slightly modified Ahmed model is used to study aerodynamic characteristics of ducted models and how ducting would contribute to the reduction of energy consumption due to aerodynamic resistance. Furthermore, energy harvesting concept is also introduced as an alternative to improve energy efficiency. Three-dimensional, incompressible, and steady flow governing equations were solved by CFD code (PHOENICS ver.2018) with extended turbulent model proposed by Chen-Kim (1987). From the study, it was found that the total drag was reduced over 15% on the opened front body than the closed one and the kinetic energy harvested in the flow duct is about 15% of the energy consumed due to aerodynamic resistance with M4 model compared to the original blocked model at higher speeds.
