Abstract

Pengaruh turbulator terhadap kinerja aliran turbulen pada double tube heat exchanger dapat memecah (partitioning) dan mengganggu (blockage) pola streamline dari fluida yang mengalir ke saluran pipa dalam (inner tube) sehingga mengakumulasi aliran turbulensi dan meningkatkan laju perpindahan kalor dalam pipa. Penelitian Louvered strip twisted ini memiliki variasi sudut serang (q = 15°, 25°, 30°) yang terpasang ditengah pipa bagian dalam dan searah aliran fluida masuk. Laju aliran fluida (air) panas di bagian pipa dalam diteliti dengan interval 400 lt/jam sampai 900 lt/jam dan laju aliran air dingin di bagian pipa luar konstan 900 lt/jam. Kinerja dari double tube heat exchanger meliputi laju perpindahan kalor (QΔLMTD), faktor gesekan (f), NTU (Number of Transfe Unit). Data hasil pengujian dari masing – masing sudut serang turbulator ini dibandingkan data tanpa turbulator (plain tube),  secara keseluruhan terjadi peningkatan laju perpindahan kalor sebesar 40 % sampai 72 % dari pada tanpa turbulator serta menghasilkan faktor gesekan dari 51 % sampai 61 %. Dengan performance ratio rata –rata tertinggi pada turbulator dengan sudut 30O sebesar 0,995.
