Abstract

Wind tunnel merupakan peralatan yang untuk melakukan pengujian aerodinamika terhadap suatu model, seperti pesawat atau mobil. Wind tunnel pada tugas akhir ini dibuat untuk mendukung penelitian dibidang aerodinamika dan memberikan fasilitas untuk tugas akhir turbin angin. Tujuan pelaksanaan tugas akhir ini adalah untuk menguji keseragaman aliran pada instalasi wind tunnel tipe aliran terbuka. Pengujian dilakukan di 4 macam posisi aliran fluida. Pertama, pengujian keseragaman di depan fan motor listrik dengan 49 titik pengujian. Kedua, pengujian keseragaman di depan honey combs dengan 49 titik pengujian. Ketiga, pengujian keseragaman aliran di bagian sebelum test section dengan 49 titik pengujian. Keempat, pengujian keseragaman aliran di bagian setelah test section dengan 16 titik pengujian. Fluida yang digunakan adalah udara. Berdasarkan hasil pengujian dan analisa data dapat disimpulkan bahwa, pada posisi 1 aliran fluida masih belum seragam dan tidak terarah dengan selisih kecepatan tertinggi dan terendah yaitu 8,1 m/s, aliran mulai seragam pada posisi 4 dengan selisih kecepatan tertinggi dan terendah yaitu 0,6 m/s . Kata kunci : wind tunnel , head , aliran udara. Wind tunnel is the equipment for testing the aerodynamics of the model , such as a plane or a car . Wind tunnel in this project designed to support aerodynamics research and provide facilities for the final project of wind turbine models. The aim of this project is to test the uniformity of the flow in the open flow type wind tunnel. Tests conducted in 4 different positions. First , position is the front of the fan with a 49 point test . Second , position is in front of honey combs with 49 test points. Third , position is before the test section with 49 points . Fourth , position is after the test section with 16 point test . Fluid used is air . Based on test results and analysis of the data it can be concluded that , at the first position the flow is still not uniform fluid flow and the difference between highest and lowest speed is 8.1 m/s , the flow started to uniform at fourth position with velocity difference between the highest and the lowest is 0 , 6 m / s . Keyword : wind tunnel , head, fluid flow.
