The aerodynamic aspect plays a crucial role in product design, as it affects the product's ability to pass through fluids (such as air or water) and contributes to shaping the aesthetic design. The science of aerodynamics has evolved since the Wright brothers designed the first aircraft, which achieved a height of 37 meters for 12 seconds [1]. Their discovery laid the foundation for aeronautical engineering, including the field of aerodynamics. Aerodynamics is defined as the study of fluid flow around solid objects of various shapes. Product designers iterate on shapes using various principles of physics, particularly fluid mechanics. Bernoulli's principle is one of the relevant laws for studying the characteristics of fluid flow on surfaces, and modern simulation software aids designers in analyzing aerodynamic shapes. Aerodynamic principles have been applied to various applications, including aircraft, automotive vehicles, rockets, trains, ships, and even structures and buildings.
