Boundary layer analysis with Pitot tube
Investigation of the boundary layer on a flat plate with flow along the plate; two different surfaces
Features
- investigation of the boundary layer on a flat plate with flow along the plate
- two plates with different surfaces
- Pitot tube for measuring the total pressure
Learning objectives/experiments
- measure total pressure with Pitot tube
- measure static pressure, in the measuring section of HM 170
- determine velocity via dynamic pressure
- study the vertical velocity profile at the measuring point
- study the boundary layer thickness
- influence of surface roughness on the boundary layer
Specification
