Abstract

Pengaruh turbulator yang berbentuk Louvered strips terhadap laju perpindahan panas dan faktor gesekan 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. Turbulator Louvered strips memiliki variasi sudut serang (q = 15°, 25°, 30°) yang terpasang ditengah-tengah 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. Data hasil pengujian dari masing – masing sudut serang turbulator ini dibandingkan data tanpa turbulator (plain tube),  secara keseluruhan terjadi peningkatan laju perpindahan kalor sebesar 26% sampai 58% dari pada tanpa turbulator serta menghasilkan faktor gesekan dari 25% sampai 40%. Dengan performance ratio rata –rata tertinggi pada turbulator dengan sudut 30O sebesar 0,948.
