There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterised by chaotic motion and large amounts of mixing. In this ...

The size of the wake decreases, indicating that the boundary layer separation on the cylinder or sphere occurs further along the surface than before. What has happened? The phenomenon is related to ...

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 ...
