Development of Learning Compact Wind Tunnel for Transportation Technology Class

A learning compact wind tunnel was developed in order for the student to increase the interests and attitudes in transportation technology. The developed wind tunnel has some performances and characteristics as follows: (1) The Fluid-flow field uniformity of developed wind tunnel was increased from 21.85 % to 2.43 % by providing the honeycomb apparatus, and maximum velocity of fluid-flow field is 6.33 ㎧ with test section size of 100 ㎜ × 100 ㎜. (2) The developed wind tunnel will enable the students to have the concept of qualitative and quantitative understanding on transportation field such as airplanes, automobiles, and so on. (3) A hands-on education of transportation field will be carried out with the developed wind tunnel, and the developed wind tunnel also can be used for the improvement of existing teaching-learning environment of class.
