Wind tunnels are important tools used in physics and engineering, with a wide range of usability and applications in industrial, research, and educational settings. A wind tunnel holds an object steady while generating airflow over it, often to study the interaction between the object and the airflow. The design of wind tunnels can be very costly, extensive, and difficult to implement. This paper analyzes literature on wind tunnels to compile a method for designing a portable wind tunnel suitable for educational and demonstrative purposes. The method includes design guidelines for each component, including the test section, contraction, settling chamber, honeycomb, diffuser, and fan section. A blueprint for a wind tunnel with specified dimensions is presented. The blueprint is designed to fit a Boeing 747-200 model, scaled at 1:390, and therefore have a 40 cm long test section with a 20x20 cm square cross-section. The designed wind tunnel achieves a velocity of 5 m/s in the test section. Emphasizing portability, simplicity, and functionality, this wind tunnel design enhances educational experiences, making complex fluid dynamics concepts accessible and engaging for students.
