[DESIGN AND FABRICARION OF SMALL WIND TUNNEL FOR FLOW VISUALIZATION]

The objective of this report is to provide an overview of what have been done in
completing the Final Year Project Course. The main content of project work has been
divided into five parts, comprises of:
• Feasibility Study and Conceptual Design
• Design activities - also known as Design Basis Memorandum
(DBM)
• Fabrication activities
• Tunnel testing result and procedure
• Alternative for flow visualization
Feasibility study included literature review for aerodynamics and wind tunnel
theory. The research has been done to develop conceptual design consisting of wind
tunnel type and its general configuration.
Summary of design, fabrication and tunnel testing activities has been developed in
methodology section and their respectively section to give quick view to reader of
activities involved during project stages. Major problem occurred during project
implementation and the method used to overcome the problems has also been identified.
In addition tools required for completing this project will also be discussed in their
respective area.
The scope of study for this course is not very specific to one area only and it
determined by the requirement that had been discussed with the respective supervisor.
Some of the area concerns of the project have been achieved in form of computer design
analysis, aerodynamics analysis, wind tunnel configuration, fabrication activities and
Computer Aided Design. The method or action that has been used and taken will be
specified in this report in detail. The assessment of this course really helpful for me to
explore many new things independently and to gain the knowledge as much I could
through the working experience.

At the end, the tunnel can be specified as subsonic, small scale wind tunnel,
operating at ~llm/s and average turbulence intensity at -0.8% and driven by 115m3/min
exhaust fan.
