Studi Numerik Analisa Pengaruh Variasi Longitudinal dan Transversal Pitch terhadap Performa Fin and Tube Heat Exchanger
Abstract
Abstrak
Fin and tube heat exchanger banyak digunakan dalam sistem pendingin, petrokimia, dan aplikasi HVAC&R karena pembuatannya lebih mudah, konstruksinya sederhana, rendah biaya, dan relatif mudah dalam perawatan menjadikannya salah satu yang paling umum digunakan. Peningkatan kebaikan perpindahan panas pada fin and tube heat exchanger telah banyak di investigasi guna untuk meningkatkan performanya. Riset ini dilakukan untuk mengetahui pengaruh variasi rasio arah longitudinal dan transversal pitch pada fin and tube heat exchanger terhadap performa termalnya. Metode numerik menggunakan program komputer Computational Fluid Dynamics digunakan pada riset ini. 2 variasi rasio diajukan dalam riset ini yakni variasi untuk arah longitudinal pitch 18,05; 17,05; 16,05; 15,05; 14,05 (mm) sedangkan arah transversal pitch 11,7; 10,7; 9,7; 8,7; 7,7 (mm) dengan variasi kecepatan aliran fluida 0.5 m/s, 1 m/s, 1,5 m/s, 2 m/s, 2.5 m/s, 3 m/s, dan 3,5 m/s dengan heat flux konstan sebesar 100 W. Hasil terbaik penelitian ini di dapatkan pada variasi rasio arah longitudinal pitch 14,5 mm dengan nilai koefisien perpindahan panas sebesar 97,24 W/m²K, sedangkan rasio arah transversal pitch sebesar 11,7 mm dengan nilai koefisien perpindahan panas sebesar 107,82 W/m²K. Hasil tersebut mengkonfirmasi bahwa variasi rasio arah longitudinal pitch 14,5 mm dan rasio arah transversal pitch sebesar 11,7 mm dapat digunakan untuk aplikasi praktis dan dapat diterapkan secara langsung dilapangan.
