HM 170.24

Boundary Layer Plate with Probe

Technical Description

The experimental set-up is placed in the measuring section of the HM 170 Educational Wind Tunnel. The set-up consists of 2 plates of different surface roughness, a plate bracket, a Pitot probe for velocity measurements and the bracket for the probe. To be able to measure the flow field in a vertical direction, the Pitot probe can be very precisely adjusted using a micrometer drive. To be able to measure the velocity at different flow lengths, the plate can be moved in the direction of the flow. If, to measure the static pressure, the measuring gland on the bracket is connected together with the probe connection to a slanted tube manometer, the velocity distribution in the air flow can be determined.

Learning Objectives / Experiments
