“…K is a constant that represents the c, r f , b e , and h D terms, and it is determined by initially solving equation ( 8) with a prescribed realistic on-road value of fuel consumption.

The average distance between those cities is 450 km, so the analysis adopted a distance of 400 km, which approximately represents the part of the highway road, that is, it neglects the routes in slow speed roads or streets.…”

In the automotive industry, the implementation of drag reduction systems has provided considerable decreases in fuel consumption. These outcomes are in line with the increasing demands of the environmental regulations and consumers’ requirements. Although some studies explain how aerodynamic devices reduce the aerodynamic drag on light and heavy vehicles such as Ahmed bodies and trucks, buses have received almost no attention. For this reason, the flow over the Marcopolo Paradiso 1200 G7 commercial bus and the influence of several aerodynamic devices on the drag force and fuel consumption of the bus are discussed in this article. Three distinct devices (vortex generators, lateral devices, and rails) were proposed after flow visualization tests on the baseline bus. Thus, the entire evaluation consisted of 11 arrangements by combining the three aerodynamic devices. The changes in drag due to all arrangements are estimated using wind tunnel tests, which are validated using Computational Fluid Dynamics simulations. The fuel consumption is evaluated in a simplified long-haul driving cycle between two cities. The devices were able to alter the flow behavior on the bus, resulting in a maximum decrease of 8.63% in the drag coefficient and 3.92% in fuel consumption. Given that the devices used are just first prototypes, we estimate that greater reductions can be achieved with optimized systems. Likewise, this paper probably leads to real applications in other commercial buses due to the evident drag reductions.

“…Understanding the principles of fluid dynamics and their impact on drag is crucial to the design and function of cars (Acevedo-Giraldo et al, 2018). Since adopting gas-powered vehicles in the late 19th century, cars have become integral to our society (Forrester, 2020).…”

The automotive industry has witnessed a significant push towards increased fuel efficiency and reduced carbon emissions. Among many factors influencing overall vehicle efficiency, aerodynamic drag is a critical consideration, accounting for a substantial portion of fuel consumption. Our investigation focused on the drag coefficients of three prominent 2023 passenger car models – the Toyota Corolla, Hyundai Elantra, and Kia Soul. Using ANSYS Fluent to perform computational fluid dynamics, we demonstrated an inverse correlation between drag force and gas mileage, underlining the significance of aerodynamic design in fuel efficiency. Notably, the Hyundai Elantra emerged as the most aerodynamically efficient of the three vehicles, followed closely by the Toyota Corolla. In contrast, the boxier-designed Kia Soul exhibited significantly higher drag coefficients and drag forces, rendering it the least efficient of the trio. These findings emphasize the importance of environmental factors in car design. Shaping aerodynamic profiles directly impacts fuel efficiency, stability, and overall performance.
