Prandtl (Ludwig Prandtl)

Ludwig Prandtl was a pioneering physicist and engineer who developed key ideas in fluid dynamics, particularly the concept of the boundary layer. This is the thin region of fluid (like air or water) close to a surface where flow speed changes dramatically due to friction. Understanding boundary layers helps explain how objects like airplanes generate lift or how rivers flow smoothly or turbulently. Prandtl's work laid the foundation for modern aerodynamics, enabling better aircraft design and improving our understanding of fluid behavior around structures. His insights have been fundamental in advancing engineering, physics, and aeronautics.
