Pengaruh Jarak Baffle terhadap Unjuk Keria Termal dan Penurunan Tekanan pada Alat Penukar Kalor Shell and Tube Susunan Segitiga

Abstract

This research is aimed at knowing the ffict of bffie spacing toward thermal performance and pressure drop of shell and tube heat exchanger of triangle arrangement by Jlowing water as hot fluids on the tube side and air as cold Jluids on the shell side. The test is done by one-shell-pass and one-tube-pass heat exchanger as input parameter of single segment buf/le, (bafrle cut of 22.61%o), and six various bafrle spacing- 36 mm, 40 mm, 45 mm, 5l mm, 59 mm, 7l mm with its six various air velocity and constantJlow rate hot water respectively. Where as the output parameter which is reached for air temperature is around 50-650C. The result of the research showed that a maximum thermal performance (cofficient heat transfer) with Nusselt number Q,{u) and minimum pressure drop withfrictionfactor (fl is found in 45 mm of baffle spacing. It is also found that the empirical correlation between Nusselt nimber-(Nu)indfrictionfaltor (fl is governed-by Nu: 0,16622914 * R o't""'!l fo, 12g42,7314 < Re < 49574,0706 and f : i,606031 Re'0'262e3 (Lu/D)o't"t3t'for 12842,7314 < Re < 49574,0706 and 0,27 SLb/D,<0,54
