1-
Adjust the light assembly by means of the clamps until the light guide obtains
a desirable position within the channel.
2-
Place the anode assembly in position within the working section of the channel
immediately downstream of the light guide.
3-
Place the cathode assembly in a central position in the channel
4-
Switch on the SUPPLY, PUMP and LAMP switches.
5- Adjust the pump delivery valve
to provide a fluid flow, which is commensurate with stable two-dimensional
conditions.
6-
Place the object over the flow will be visualized and observed the streamlines
in the flow.
Problem We Have At Setup the Experiment
1- We found
cut off in cathode wire so we welded it
2-
We didn't found suitable place to take results in so we have to bring black
cover and supports and we set a dark place
Data Analysis and Reporting Requirements
The
streamlines are symmetric about the x-axis in front of the body for the
cylindrical model. Streamlines are tangent to the direction flow at every point
in the flow field at a given instant. Also flow separate when meet an obstacle
in viscous flow, but not in inviscid flow. By the way, they are not symmetric
about the x-axis behind the body for the cylindrical model according to our
observations. Vortex occurs behind the cylindrical model in viscous flow. The streamlines
are symmetric about the x-axis in front of the body for the aerofoil model.

Conclusion:-
The flow over along cylinder with its axis
parallel to the mean stream results in the development of a very thick boundary
layer compared to cylinder diameter. This result has been document in several
journals.
At this stage of the project the
experimental data is recorded on a standard VHS type and detailed analysis is required
to give some insight into the flow behavior.
