FLAT PLATE BOUNDARY LAYER MODEL

Shows boundary layer development and separation. The model is a flat plate that spans the full width of the AF1450S wind tunnel working section. It has aerodynamically shaped blocks mounted across the plate at different distances from the leading edge. Each

block has five tapping points at different heights along its leading edge. Each tapping connects to flexible, numbered tubing that routes outside the wind tunnel. Students can connect the tubes to other optional pressuremeasurement instruments.

The tapping points allow students to measure the stagnation pressure. They use this to find the velocity at different heights from the surface and at different distances from the leading edge. This allows students to find the growth of the boundary layer along the plate.

On the trailing edge of the plate is a hinged flap. Students can adjust the angles of both the plate and the flap independently. This lets them create different arrangements to control pressure distribution and the boundary layer.

The surface of the plate has small ‘tufts’ to help students see the air flow around the surface of the plate.
