Abstract
Jenis heat exchanger pada dunia industri yang sering digunakan adalah shell and tube heat exchanger. Baffle merupakan salah satu komponen utama dalam desain shell and tube heat exchanger. Salah satu fungsi dari baffle yaitu untuk mengarahkan aliran dalam shell dan menyangga susunan tube yang dapat mencegah terjadinya getaran. Pada penelitian dilakukan terhadap kinerja heat exchanger tipe shell and tube dengan variasi jarak antar baffle jenis flower dengan susunan baffle secara selang-seling. Penelitian ini dilakukan dengan metode computational fluid dynamics (CFD) dengan variasi jarak antar baffle yaitu 57 mm, 49 mm, 45 mm dan 41 mm. Hasil simulasi menunjukkan bahwa pada jarak antar baffle 49 mm menghasilkan laju perpindahan panas paling tinggi diantara variasi lain yaitu sebesar 192232,2114 Watt/m. Pada hasil simulasi juga menunjukkan terjadi adanya recirculation flow yang terlihat melalui vektor kecepatan dan streamline.

The type of heat exchanger in the industrial field oftenly used is a shell and tube heat exchanger. The baffle is one of the main components in the shell and tube heat exchanger design. One of the functions of the baffle is directing the fluid flow in the shell and support the arrangement of tubes that can prevent vibration. The research was conducted on the performance of shell and tube type heat exchanger with variations in the distance between flower type baffles and alternating baffle arrangements. This research was carried out using computational fluid dynamics (CFD) method with variations in the distance between baffles which were 57 mm, 49 mm, 45 mm and 41 mm. The simulation results shows that the distance between 49 mm baffle produces the highest heat transfer rate among other variations, which is 192232,2114 Watt / m. The simulation results also shows that there is a recirculation flow that is seen through a velocity vector and streamlines.
