Abstract

Efisiensi energi dalam sistem industri sangat bergantung pada kinerja fin-and-tube heat exchangers (FTHE), sehingga peningkatan kapasitas perpindahan panas menjadi fokus utama dalam upaya konservasi energi. Salah satu metode yang terbukti efektif untuk meningkatkan laju perpindahan kalor adalah penggunaan vortex generators (VGs), yang menciptakan pusaran aliran guna memperkuat pencampuran fluida di dalam penukar panas. Studi ini melakukan simulasi numerik untuk menganalisis kinerja delta winglet vortex generators (DW VGs) dan perforated delta winglet vortex generators (PDW VGs) dalam meningkatkan efisiensi termohidrolik. Kecepatan aliran divariasikan antara 0,4 m/s hingga 2 m/s dengan interval 0,2 m/s, serta digunakan variasi sudut serang sebesar 10° dan 15°. Evaluasi performa dilakukan menggunakan parameter Performance Evaluation Criteria (PEC), yang dihitung berdasarkan rasio peningkatan koefisien perpindahan panas terhadap peningkatan faktor gesekan. Hasil simulasi menunjukkan bahwa konfigurasi DW VGs memiliki nilai PEC yang lebih tinggi dibandingkan PDW VGs, menandakan efisiensi perpindahan panas yang lebih rendah walaupun tanpa peningkatan pressure drop yang signifikan.
