FLAT PLATE BOUNDARY LAYER MODEL ROUGHENED AND SMOOTH

A pair of boundary layer models with a mounting plate, also a pitot and a static probe for investigating boundary layer. One plate is roughened, the other smooth to allow comparisons on boundary layer growth.

The Pitot and static tubes fit to the Pitot-static XY traverse to allow pressures to be measured very close to the flat plate's surface. The traverse allows the boundary layer to be measured at multiple positions.
