Design, build and commission our own wind tunnel is a large project. It started in April 2013 and expected to complete in March 2015. A lot of the faculty staff is involved, they are from the Department of Mechanical and Materials and the department of Civil and Structure, the Faculty of Engineering Built Environment. Final year students and research students have been involved in the project. Upon successful commission, the wind tunnel would be able to perform for experiments with velocity up to 30 m/s with test section 3.0 m (length) x 0.5 m (height) x 1.0 m (width). The wind tunnel is an open-return type, power by 18 kW motor-fan. It has a variable speed drive (VSD) capability i.e. air velocity could be control using programming codes.

The wind tunnel has already have its own 2 axis traversing system, a particle image velocimetry (PIV) and bunch of delicate equipment such as hotwire anemometry, pitot-tube-pressure transducer, temperature, room humidity and barometric pressure sensor.

The design of the wind tunnel is undertaken in-house where chief designer is Dr. Wan Aizon Wan Ghopa supported by PhD student Ashraf A’mer Abbas Alsaffar and final year student (FYP) Muhammad Firdaus Mohd. The Fabrication is led by Master’s student En. Mohamad Izhar Ghazali (from Malaysian-France Institute) who specializes in metal tooling. Equipment set up (such as location and PIV), security and logistic led by Dr. Wan Hanna Melini Wan Mokhtar . PIV set up by En. Zulkhairee.

The detailed planning, design and construction of the wind tunnel has been documented in this article title The Development of a Multi-Purpose Wind Tunnel (selected pages). Some of the important Scilab codes to support automatic operation is provided in this document (WT Connectivity).
