At supersonic speeds, however, sufficient heat is generated by viscous dissipation in the boundary layer to change the density of the fluid significantly. Figure 8. Flow in a channel, showing boundary ...

The tunnel operating conditions were chosen to give a Reynolds number range so that at the lowest Reynolds number the flow will be laminar (even on the tunnel walls), and at the highest Reynolds ...

The Boundary Layer Wind Tunnel in the Hele-Shaw Laboratory within the ... It serves fields such as fundamental and applied aerodynamics, aeroacoustics, environmental flow, air pollution, and wind ...
