Abstract

Penukar panas merupakan alat yang digunakan untuk memindah energi berupa kalor dari dua atau lebih aliran fluida Yang berbeda temperatur. Alat penukar panas yang digunakan adalah jenis shell and tube dengan baffle seperempat lingkaran yang disusun melingkar/helical seperti ulir pada sekrup ( Helixchanger ) dengan sudut kemiringan 10. Tugas akhir ini bertujuan untuk mengamati pengaruh bentuk helical baffle terhadap unjuk kerja Helixchanger berupa koefisien perpindahan panas konveksi sisi shell (h), laju perpindahan panas ( q J, effectiveness ( & ), dan pressure drop sisi shell ( M J. Pengujian dilakukan dengan dua macam arah aliran, yaitu aliran searah dan berlawanan arah Perpindahan panas yang terjadi adalah perpindahan panas satu fase, dengan temperatur masuk fluida panas dijaga konstan 6rl C. Aliran fluida panas berada pada sisi tube sedang fluida dingin pada sisi shell. Debit fluida dingin divariasikan sebesar 600, 700, 800, 900, 1000 (Lijam) sedang debit fluida panas sebesar 1800, 1900, 2000 (Lijam). Dari pengujian dan perhitungan yang telah dilakukan didapatkan hasil bahwa koefisien konveksi sisi shell (he), laju perpindahan panas sisi shell ( q c), effectiveness ( & ) , dan pressure drop sisi shell ( M J aliran counter lebih tinggi dibanding aliran paralel. Pada aliran counter didapatkan nilai q cold sebesar 3570.3 - 5588.98 3W, he sebesar 279.53 - 1135.67 W/m2.K, 0.18- 0.307, dan M e sebesar 0.16 - 0.19 kg/cm2 . Pada aliran paralel didapatkan nilai qeotd sebesar 3349.8 - 4641.16 W, he sebesar 264.46 - 840.17 W/m2.K, dan e sebesar 0.16 - 0.27, dan M e sebesar 0. 07- 0.1 kglcm2

A heat exchanger is a tool used to transfer energy in the form of heat from two or more fluid flows at different temperatures. The heat exchanger used is a shell and tube type with a quarter circle baffle arranged in a circle/helical like a screw thread (Helixchanger) with an inclination angle of 10. This final project aims to observe the effect of the helical baffle shape on the performance of the Helixchanger in the form of the shell side convection heat transfer coefficient (h), the heat transfer rate (q J, effectiveness ( & ), and the shell side pressure drop ( M J). Tests are carried out with two kinds of flow directions, namely unidirectional and countercurrent flow. The heat transfer that occurs is a single-phase heat transfer, with the inlet temperature of the hot fluid kept constant at 6rl C. The hot fluid flow is on the tube side while the cold fluid is on the shell side. The cold fluid discharge is varied by 600, 700, 800, 900, 1000 (Li hours) while the hot fluid discharge is 1800, 1900, 2000 (Li hours). From the tests and calculations that have been carried out, the results show that the shell side convection coefficient (he), the shell side heat transfer rate ( q c), effectiveness ( & ), and shell side pressure drop ( M J counter flow is higher than parallel flow. In counter flow, the q cold value is 3570.3 - 5588.98 3W, he is 279.53 - 1135.67 W/m2.K, 0.18- 0.307, and M e is 0.16 - 0.19 kg/cm2. In parallel flow, the qeotd value is 3349.8 - 4641.16 W, he is 264.46 - 840.17 W/m2.K, and e is 0.16 - 0.27, and M e is 0. 07- 0.1 kglcm2
