Boundary Layer Apparatus.
Boundary Layer Apparatus Technical Description Using the Boundary Layer Apparatus in combination with the Air Flow Bench, boundary layers can be experimentally investigated. The experimental set-up is fitted to the nozzle using quick action fasteners. The plate to be investigated with a longitudinal flow is slid into the unit. The plate has two different surface finishes for performing experiments. A thin Pitot tube is used to measure the dynamic pressure in the boundary layer; the Pitot tube is moved towards the plate using a micrometer adjustment bolt.
