Use in Fluid Dynamics II lab.

A flat plate is in a transparent working section so that a boundary layer forms along it. A sensitive, wedge-shaped Pitot tube mounted in a micrometer traverse allows students to measure velocity in the boundary layer. Both laminar and turbulent layers may be formed.

Experiments include measurement of the velocity profile:

  • in laminar and turbulent boundary layers,
  • in the boundary layer on rough and smooth plates,
  • in the boundary layer at various distances from the leading edge of the plate, and
  • in the boundary layer on plates subject to an increasing or decreasing pressure gradient in the direction of flow (using the removable duct liners supplied).
