What Does BDL Stand For?

BDL stands for Boundary Layer

BDL, or Boundary Layer, refers to the thin region of fluid near a surface where the effects of viscosity are significant. In the context of aerodynamics and meteorology, this layer plays a crucial role in influencing flow dynamics, heat transfer, and mass exchange between the surface and the surrounding fluid. Understanding the characteristics of the boundary layer is essential for accurate predictions of drag, lift, and turbulent flow patterns, making it a fundamental concept in engineering and environmental sciences.
