Fundamentals of Fluid Dynamics and Drag Forces
Fluid dynamics is the study of how fluids—liquids and gases—move and interact with objects. It provides the foundational principles necessary to understand how side panel contours influence airflow and drag. Understanding flow behavior around surfaces is essential for optimizing aerodynamic performance.
Drag forces are resistive forces generated as a fluid moves past an object. These forces depend on factors such as the vehicle’s shape, surface smoothness, and the flow’s velocity. In the context of side panels, minimizing drag involves controlling how air interacts with panel contours, reducing turbulence and wake formation.
Key concepts relevant to the impact of side panel contours on drag include:
