WebMay 24, 2024 · Figure: Hydrodynamic boundary layer around the profile of a wing. In the case of sharp transitions or when flowing around blunt bodies, however, the fluid is often no longer able to follow the profile. The boundary layer or flow begins to detach itself from the body surface. This is referred to as a boundary layer separation or flow separation. WebThe drag coefficient quantifies the drag or resistance of an object in a fluid environment. Dynamic (Absolute) Viscosity - Converting Chart Convert dynamic viscosity values between units like Poiseuille - Poise - centiPoise and more.
