“…Despite some research on the aerodynamic design of vehicle bodies, specifically for fuel consumption reduction, the information regarding the influence of variations in the upper-side inclination of vehicles on aerodynamic drag is still very rare. Previous research has been carried out by researchers regarding the effect of the specific tilt of the rear body of a car on reducing drag [22][23][24]. According to the theory that the slope angle of the rear roof can delay the separation further back so that the wake area is smaller thus the drag force is also smaller.…”

Currently, golf cars as a means of transportation vehicles have been used at large universities spread over large areas, expensive hotels and housing complexes and most recently for travel comfort, namely in the hotel industry. Theoretically, aerodynamic drag on transportation vehicles contributes around 50-60% to vehicle fuel consumption. The aim of this research is that by utilizing the upper-side inclination angle of the golf car, it can reduce aerodynamic drag and automatically reduce vehicle fuel consumption. In this paper, the effect of upper-side inclination angle on aerodynamic loads on a golf cart (i.e. total pressure, turbulence kinetic energy, velocity contour, and drag force) is investigated using 3D Computational Fluid Dynamics. The results of the research show that at the same speed, the greater the upper-side inclination angle of a golf cart the greater the drag force obtained. A tilt angle of 600 with a speed of 20 km/h produces the lowest drag force value. When compared to standard (00 tilt angle) the reduction in drag is around 38.06 %. In conclusion, that 3D Computational Fluid Dynamics can simulate the influence of the upper-side inclination angle on the aerodynamic load from the golf cart.
