EXPERIMENTAL ASSESSMENT OF AIRFLOW PATTERNS OVER PICKUP TRUCK’S CARGO AREA USING BED COVERS

Abstract
Abstract - Automobiles take on various forms and interact with the surrounding air when in motion. This interaction, known as aerodynamics, studies how solid bodies influence the flow of air around them. The shape of these solid bodies plays a crucial role in determining their resistance to the airflow. Factors such as additional cargo and loads can significantly impact an automobile's aerodynamics, which is essential for safe transportation of people and goods. Despite stringent safety measures, vehicle-related accidents remain a significant concern. This study aims to investigate the effects of added cargo and covers on an automobile's performance. The introduction of these elements alters the vehicle's original shape and approved design for safe operation. To examine these changes, we conducted experiments using a 1:27 scale model of the F150 pickup truck, one of the most prevalent pickup trucks in the United States. Various loads with different shapes and weights were tested at a constant speed. The presence of additional freightage introduces unwanted drag or lift, resulting in reduced fuel efficiency and potentially unsafe driving conditions. To mitigate these effects, we employed an adjustable external shell on the F-150 pickup truck, creating a controlled aerodynamic configuration. The results were visualized using colored powder, serving as a medium to highlight the interaction of air with the vehicle's exterior. This paper contributes to standardizing the geometric design of external shells, considering the unique nature of each load and its placement on the vehicle. Additionally, it provides real-time data for comparison, aiming to enhance our understanding of the complex interplay between cargo, covers, and vehicle aerodynamics.
