HM 225.02

Boundary Layer Apparatus

Technical Description

Using the HM 225.02 Boundary Layer Apparatus in combination with the HM 225 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.

Learning Objectives / Experiments

· Familiarisation with the internal friction of gases
· Laminar and turbulent boundary layer at the flat plate

Features

· Accessory for boundary layer experiments on the HM 225 Air Flow Bench
