At a Reynolds number between 10^5 and 10^6, the drag coefficient takes a sudden dip. The size of the wake decreases, indicating that the boundary layer separation on the cylinder or sphere occurs ...

Scientists at the University of Stuttgart's Institute of Aerodynamics and Gas Dynamics (IAG) have produced a novel dataset ...

The drag coefficient, given similar wind speeds, is smaller for smaller-radii storms; enhanced sea spray by short or breaking waves is speculated as a cause. A fitting technique of dropsonde wind ...

The hydrodynamic and water quality modelling of the complex coastal water environments requires detailed knowledge of the forcing and boundary conditions. It also requires knowledge of how the bed ...

Flow in a channel, showing boundary layers near the walls. Figure 9. Flow over an airfoil, showing boundary layers near the surface, and the formation of a wake. Inside a pipe or a channel, the ...
