Abstract

This dissertation is compiled on the study of Development and Improvement on subsonic wind tunnel developed in Universiti Teknologi Petronas (herein after is called UTP). The objective of this study is to design and develop a new open circuit subsonic wind tunnel that can operate under II m/s - 15 m/s. Basically, the project was divided onto two phases. In Phase I, the scope of study was to cover the literature review on theory regarding the sub sonic wind. The guidelines for the design then were selected and compiled to engineer a new sub sonic wind tunnel that meets the criteria given. The study in Phase I also covered the justification on fan selection and proper contraction ratio. In Phase II, the air flow quality such as turbulence intensity and velocity variations were investigated to verify the developed wind tunnel. The scope of study in Phase II included the understanding of working principle of hot wire anemometer as the tool needed to measure velocity and turbulence intensity. The methodology of approach to achieve the objective started from the literature review related to the airflow quality. Based on the literature review in phase II, an experiment was conducted to determine the velocity variation and the turbulence intensity in the test section. A constant temperature anemometer as one type hot wire anemometer is being used throughout the experiment. The result is obtained by using the Streamline/Streamware software. The sensor used for the experiment was ID(55Pll-Gold Plated Miniature wire probe) sensor due to the unavailable 2D(55P61-X wire probe) sensor during the experiment. . Based on the results obtained, it showed that the velocity of air throughout the test section was about 11 m/s - 12 m/s which meet the first objective of the project. The turbulence level was quite low although exceed the constraint of less than 0.1 %. This was basically due to the absent of the honeycomb in the settling chamber. However, the project can be concluded to be successful as it meet one of the design constraint which to operate under l 0 m/s - 15 m/s.
