Uji Eksperimental Pengaruh Jarak Baffle terhadap Unjuk Keria Termal dan Penurunan Tekanan pada Alat Penukar Kalor Shell and Tube I-2 Pass Susunan Tabung Segi Tiga

Abstract

An experimental and theoretical iwestigation wos made to find out the effect of the ffictiveness atid pressure drop oti the 1-2 pass shell and rube hem aichaiigar with different bafrle distance for staggered tube arrdngement. A heat exchanger using segmental bafrle wtth 23,85% baffle cut is tested with dffirent baffle distance which are: 36 mm, 40 mm, 45 mm, 45 mm, 5l mm, 59 mm, and 7l mm. The experimental results showed that a mmimum coeficient heat transfer with Nusselt number (Nu) and minimum pressure drop with friction factor fi is found in 45 mm of bafrle distance. It is alsofound tlat the empirical correlation between Nusselt number (Nu)- andfrictionfactoi (fl is governed iy Nu:0,1015 Re0'63e3 and f :4,1728 Re'0'281e8 .&/D)0'"337o, , 98;46,33 < Re < 37645,5A andfor 0,27 SL/D.50,54
