| Summary: | The research focuses on the application of aerodynamics beyond aviation,
particularly in heavy vehicle design. Traditionally associated with flight, aerodynamic
principles play a vital role in minimizing drag for vehicles and trailers, as well as assessing
wind stresses on various structures. Heavy vehicles, such as tractor-trailers and buses, consume
a significant amount of fuel, and a substantial portion of this consumption is attributed to
overcoming aerodynamic drag. The drag force acting on these vehicles increases fuel
consumption, making it imperative to minimize drag to enhance fuel efficiency and reduce
operational costs. Additionally, reducing drag can lead to improved stability, handling, and
safety of heavy vehicles, further emphasizing the significance of aerodynamics in this context.
The study provides a comprehensive overview of heavy vehicle aerodynamics, exploring the
use of flow-control devices to reduce drag. Computational fluid dynamics (CFD) is employed
to simulate the flow field around trucks, using a steady-state formula to evaluate the software's
effectiveness in modeling contemporary truck aerodynamics. The primary objective is to
enhance the aerodynamic profile of a truck's front end and reduce drag resistance through the
implementation of an appropriate drag reduction system. This paper introduces five new
designs to compare the drag coefficient, drag force, and fuel consumption with the benchmark
design. The results show that Design 1 performs the best among all. The parameters used for
comparison include the drag coefficient, drag force, and fuel consumption, which were
analyzed using computational fluid dynamics simulations and steady-state formula
evaluations. Furthermore, the study discusses future directions for advancing the field,
emphasizing ongoing efforts to improve heavy vehicle aerodynamics and the broader
implications for the transportation industry. |
