“…Penelitian oleh Bao dan Dallman [7], mengkaji lebih detail berbagai aspek fisis terbentuknya separasi bubble yang melalui geometri berbentuk rounded backward-facing step, baik dari kajian eksperimental maupun pemodelan numerik. Penelitian tersebut dapat lebih menjelaskan evolusi lapis batas yang attach pada kontur permukaan yang bertransisi dari aliran laminar hingga menjadi turbulen, yang diantaranya dipengaruhi adanya separasi bubble.…”

Eksperimen Laminar Flow Visualization and Analysis Unit (LFA) adalah peralatan yang baru diadakan pada tahun 2019 di Laboratorium Mekanika Fluida Departemen Teknik Mesin Universitas Hasanuddin. Untuk itu, harus dipersiapkan tatacara penggunaan peralatan dalam eksperimen karakteristik aliran fluida melintasi berbagai bentuk benda dan model interaksi benda. Karakteristik penggunaan peralatan LFA, menjadi acuan untuk praktikum dan penelitian mahasiswa serta dosen. Metode eksperimen adalah dengan mengalirkan fluida melewati 3 bentuk benda dan 8 interaksi model benda (benda uji) pada 2 tingkat kecepatan yaitu 0,44 m/s dan 0,52 m/s. Selanjutnya merekam visualisasi aliran yang terbentuk pada masing-masing tingkat kecepatan dan benda uji tersebut. Hasil visualisasi menunjukkan bahwa bila bentuk benda berbeda, maka pola pertumbuhan lapisan batas, pemisahan aliran dan vortex aliran yang terbentuk berbeda. Demikian pula, untuk masing-masing interaksi antara dua benda atau lebih yang sama maupun berbeda, maka menghasilkan aliran yang berbeda.

“…Salam, et al [9]- [11], conducted a similar study regarding the effect of adding an Inlet Disturbance Body (IDB) in the form of a circular cylinder on the drag acting on a square cylinder in a tandem arrangement through a numerical simulation approach using computational fluid dynamics methods and experimental testing utilizing the subsonic wind tunnel facility. The Reynolds number used is in the range of 30.625 to 96.250.…”

The Fluid flow through circular cylinders in serieal parallel positions arranged in tandem were analyzed computationally and experimentally at nine levels of Reynolds number, ReD 34,229; 47,921; 61,612; 75,304; 88,996; 102,688; 116,379; 130.071 and 143,763 The variation in the ratio of the distance between the front and rear cylinders is determined as M / D = 0.3, M / D = 0.5, M / D = 0.7, M / D = 0.9, and M / D = 1.1. While the distance between cylinder number 2 and 3 we set constantly and determined as N / D = 5 cm. The results displayed are flow velocity with computational approach validated by flow visualization, computational pressure contour, and drag coefficient through experimental testing. The results showed that the smallest boundary layer thickness was obtained in the model with a distance ratio of M / D = 2.5, using both computational and experimental approaches. The characteristics of the minimum pressure contour and the lowest drag coefficient (CD) = 0.7572 were also obtained at the ratio of the distance M / D = 0.25 and at upstream speed of 21 m / s
