| 概要 |
The current increase in global fossil fuel costs is a severe issue, with higher number of petrol-powered automobiles on the world's highways contributing to greater air pollution. To address this issu...e, reducing vehicle aerodynamic drag has been a major topic in recent decades. In Indonesia, a mitigating effort that has been applied is the development of Si Jayaraya as a prototype urban concept vehicle built by the Batavia Team at State University of Jakarta. Vehicle is designed to compete in energy efficiency, while also addressing the issue of rising global consumption of fossil fuels and reducing air quality degradation. Therefore, this research aimed to investigate the aerodynamic quality of Si Jayaraya using numerical analysis to solve governing equations through Computational Fluid Dynamics (CFD). The calculation of trajectory lines, velocity vectors, drag coefficient, and lift force were carried out using speed changes of 15 km/h, 30 km/h, 45 km/h, and 60 km/h, respectively. The results showed that the drag coefficient was largely constant, while vehicle lift coefficient decreased in value as the speed increased, with the green flow contour on the body providing a uniform airflow pattern at all speeds. This research contributes valuable information to optimize the aerodynamic design of Si Jayaraya, thereby enhancing energy efficiency and performance in competitions. Additionally, it promotes sustainable transportation solutions to global energy challenges and environmental concerns.続きを見る
