Abstract

Para peneliti telah memperhatikan peningkatan perpindahan panas pada heat exchanger yang menggunakan generator vortex. Akibatnya, tujuan dari penelitian ini adalah untuk melihat bagaimana jumlah convex-strips vortex generator mempengaruhi peningkatan perpindahan panas dan resistansi aliran pada heat exchanger. Pemodelan tiga dimensi dilakukan dengan jumlah strip convex yang berbeda dari 4 hingga 8, 12 hingga 16, 20 hingga 24, dan 28. Strip convex tersebut ditempatkan di sekitar pipa panas. Model turbulen k-ε digunakan untuk mensimulasikan aliran fluida pada rentang bilangan Reynolds dari 3.438 hingga 15.926. Hasil penelitian menunjukkan bahwa fin dengan 24 convex-strips menunjukkan laju perpindahan panas tertinggi sebesar 58,45% dibandingkan dengan  plain fin.
