Abstract

Fan axial merupakan komponen penting dalam sistem heat exchanger (evaporator, kondensor, hydrobluh, cooling tower) yang berfungsi menghasilkan aliran udara (airflow) untuk mendinginkan ruangan secara merata. Salah satu aksesori yang digunakan untuk meningkatkan performa aliran udara tanpa penambahan energi adalah streamer, yang bekerja dengan meluruskan aliran udara agar distribusinya lebih merata di ruang dingin. Laporan magang ini membahas analisis pengaruh perbandingan penambahan streamer terhadap laju aliran airthrow pada fan axial tipe S3G500-AM06-09 di PT. XYZ. Analisis dilakukan menggunakan metode Computational Fluid Dynamics (CFD) dengan software ANSYS Fluent 2021, dengan membandingkan dua variasi model, yaitu fan nozzle yang menggunakan streamer dan fan nozzle tanpa streamer. Data kuantitatif yang diperoleh berupa nilai velocity airthrow pada enam titik jarak dari fan, sedangkan data kualitatif berupa boundary/counture hasil simulasi. Hasil simulasi menunjukkan bahwa fan nozzle dengan streamer menghasilkan aliran udara yang lebih terarah dan panjang hingga mendekati ujung dinding ruangan, namun dengan nilai velocity yang cenderung lebih rendah dan menurun seiring bertambahnya jarak dari fan. Sebaliknya, fan nozzle tanpa streamer menghasilkan velocity yang lebih besar dan fluktuatif, dengan persebaran yang lebih luas namun kurang merata dibanding penggunaan streamer. Berdasarkan hasil tersebut, dapat disimpulkan bahwa penambahan streamer efektif mengarahkan aliran udara pada zona kritis (trailing edge fan), namun untuk persebaran udara yang menyebar secara maksimal ke seluruh ruangan, penggunaan fan nozzle tanpa streamer secara kuantitas velocity lebih unggul, meskipun distribusinya kurang terarah.

Axial fans are essential components in heat exchanger systems (evaporators, condensers, hydroblu units, cooling towers) that generate airflow to cool spaces evenly. One accessory used to improve airflow performance without additional energy input is the streamer, which works by straightening the air stream to achieve more uniform air distribution in cold rooms. This internship report discusses the analysis of the effect of adding a streamer on the airthrow flow rate of an axial fan type S3G500-AM06-09 at PT. XYZ. The analysis was carried out using the Computational Fluid Dynamics (CFD) method with ANSYS Fluent 2021 software, comparing two model variations: a fan nozzle with a streamer and a fan nozzle without a streamer. Quantitative data obtained were velocity values of the airthrow at six distance points from the fan, while qualitative data were obtained in the form of boundary/contour simulation results. The simulation results show that the fan nozzle with a streamer produces a more directed and longer airflow reaching close to the end wall of the room, but with velocity values that tend to be lower and decrease as the distance from the fan increases. In contrast, the fan nozzle without a streamer produces higher and more fluctuating velocity, with a wider but less even spread compared to the streamer configuration. Based on these results, it can be concluded that adding a streamer effectively directs airflow in the critical zone (fan trailing edge), but for maximum air distribution throughout the room, the fan nozzle without a streamer is quantitatively superior in velocity, although its distribution is less directed.
