Abstract
Heat exchanger merupakan alat penukar panas yang umum digunakan pada bidang industri. Peningkatan laju perpindahan panas diperlukan agar kinerja heat exchanger semakin optimal, salah satunya adalah dengan menggunakan vortex generator. Vortex generator dapat menimbulkan olakan-olakan membujur pada aliran udara yang menuju bagian belakang tube sehingga udara yang melewati sisi kiri dan kanan tube dapat tercampur. Pada penelitian ini dilakukan dengan metode computational fluid dynamics (CFD) dengan tiga variasi susunan vortex generator yaitu single row, three rows dan staggered disertai variasi sudut serang sebesar 155°, 160°, 165° dan 170°. Hasil simulasi menunjukkan bahwa dengan adanya penambahan vortex generator laju perpindahan panas dapat ditingkatkan. Penambahan vortex generator dengan susunan single row dan sudut serang 170° menghasilkan laju perpindahan panas paling tinggi diantara variasi lain yaitu 3241,79 Watt/m atau terjadi peningkatan laju perpindahan panas sebesar 37,13% dibanding variasi tanpa vortex generator.=================================================Heat exchanger is a common device used in industrial field. An enhancement of heat transfer is required to optimize the heat exchanger performance. Additional vortex generator can be used because it creates longitudinal vortex on the air flow field and changes the direction of air passing tubes so the air will be mixed. In this research, a computational fluid dynamics (CFD) simulation study was conducted using three variations of vortex generator arrangement, single row, three rows and staggered with four angle of attack variation, 155°, 160°, 165° and 170°. The results show that additional single row vortex generator with 170° angle of attack yield highest heat flux over all variation, 3241,79 Watt/m or its enhance 37,13% heat flux compared than base variation (no vortex generator applied).
