Boundary layer studies involve the determination of the thickness of this layer and the velocity profile within it. These parameters will vary with velocity of the fluid flowing over the surface, the distance from the leading edge of the surface and the degree of roughness of the surface. When a fluid flows adjacent to a stationary surface, e.g. down a tube, the fluid immediately in contact with the stationary surface will have zero velocity. The resulting shear forces in this area will be significant and lead to high values of drag forces between the flowing and stationary surface. As a result there will be a comparatively steep velocity gradient associated with the adjacent boundary layer of the fluid. Boundary Layer Experiment accommodates these studies.
Experimental Capability:
Boundary layer growth on smooth and rough surfaces
To determine the velocity profile of the boundary layer at different distances from the sharp leading edge of a smooth test plate

The applied force is captured on the digital display along with the revolution count of the specimen. Both values can be reset and zeroed (tared) prior to the testing commencing. When failure occurs, a microswitch stops the motor and the cycles to failure are registered on the digital display. A 2800rpm motor rotates a specimen through a gear and pulley arrangement between 5600 or 1425 rpm. The specimens are held within chucks and loaded using a cantilever arrangement, with the load being applied through a screw jack mechanism with integral cantilever load cell. This Rotating Fatigue Machine Digital Apparatus has been designed to introduce students to the effects of material fatigue using a sinusoidal variation of bending stress. The count remains when the motor is not running and the ability to reset the counter has been designed in. Through an appropriate spreadsheet software printing and manipulation of data can be completed.Specially machined necked test specimens are provided in steel. A safety guard shields all rotating parts. The digital display incorporates a usb socket, which allows a host computer to be connected to the. The software supplied with the allows the capture and reviewing of data. These have a 4mm nominal neck diameter and are held in the unit using collect chucks. All tooling is provided to allow the removal and fitting of these specimens.
