Abstract

The wind tunnel is a piece of tube-structured test equipment that is forced to go fast, which is used to study the effects of aerodynamic flow on an object [1], as well as aerodynamics has a significant role in the design of a body, fins, turbines and other objects that rub directly against each other, with air or other gases. In this research, a wind tunnel is designed with a section measuring 0.5 m × 0.5 m which will be used to test direct friction modelling with the Renewable Energy Engineering Laboratory. The wind tunnel has several important parts to produce stable and laminar air in the test section, Honeycombs, Contraction, Test Section, Diffuser and Fan [2]. Determining the size of the wind is done by analytical methods to determine the power of the fan driving motor [3]. This wind tunnel uses a fan with a propeller diameter of 68 cm and uses a 400Watt electric motor drive. This wind tunnel has a maximum wind speed of 5.5 m/s in the test section, and has been tested at speeds of 0.5 m/s, 1 m/s, 1.5 m/s, 2 m/s, 2, 5 m/s, 3 m/s, 3.5 m/s, 4 m/s, 4.5 m/s, 5 m/s, and 5.5 m/s can produce stable and laminar airflow.
