PENGARUH BAFFLE CUT TERHADAP EFEKTIVITAS PENUKAR PANAS SHELL AND TUBE JENIS TRIPLE-SEGMENTAL BAFFLE

EFFECT OF BAFFLE CUT ON THE EFFECTIVENESS OF SHELL HEAT EXCHANGERS AND BAFFLE TRIPLE-SEGMENTAL TUBE TYPE

Baffle adalah penyekat di dalam shell and tube yang berfungsi untuk memperluas kontak fluida agar perpindahan panas pada kedua fluida semakin meningkat. Dari penelitian sebelumnya belum didapat baffle cut yang optimal terhadap perpindahan panas, diperlukan penelitian lebih lanjut tentang pengaruh variasi baffle cut 20%,30%, dan 40% Triple-Segmental Baffle. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh variasi baffle cut jenis orientation double-segmental baffle terhadap efektivitas pada penukar panas shell andtube.

Objek penelitian ini adalah shell and tube heat exchanger dan Triple-Segmental Baffle dengan variasi baffle cut 20%,30%, dan 40%. Pengambilan data ini menggunakan alat flowmeter, pressure gauge, dan thermocontrol. Data Hasil penelitian dianalisis secara deskriptif dan dihitung secara teoritis dimasukkan dalam tabel dan grafik.

Hasil penelitian menunjukan nilai efektivitas pada variasi potongan baffle 20% mencapai 44%, saat baffle cut 30% mendapatkan nilai efektivitas 32%, dan saat baffle cut 40% nilai efektivitas menjadi 18%. dikarenakan adanya peningkatan gesekan antara fluida dengan permukaan baffle yang terjadi karena fluida mengalir lebih lama dan banyak menyerap panas pada tube, sehingga nilai efektivitas paling optimal terdapat pada variasi baffle cut 20% dengan nilai efektivitas perpindahan panas sebesar 44%.

Baffle is a insulator in the shell and tube that serves to expand fluid contact so that heat transfer in both fluids increases. From previous studies that have not obtained an optimal baffle cut against heat transfer, more research is needed on the effect of baffle cut variation of 20%,30%, and 40% Triple-Segmental Baffle. The goal of the study was to determine the effect of variation in baffle cut type double-segmental baffle orientation on effectiveness on shell and tube heat exchangers.

The objects of the study are shell and tube heat exchanger and Triple-Segmental Baffle with variations of baffle cut 20%,30%, and 40%. This data capture uses flowmeter, pressure gauge, and thermocontrol tools. Data Research results are analyzed descriptively and calculated theoretically included in tables and graphs.

The results showed the effectiveness value of the variation in baffle cuts 20% reached 44%, when the baffle cut 30% got an effectiveness value of 32%, and when the baffle cut 40% effectiveness value to 18%. Due to the increase in friction between the fluid and the baffle surface that occurs because the fluid flows longer and absorbs a lot of heat on the tube, so the most optimal effectiveness value is in the baffle cut variation of 20% with a heat transfer effectiveness value of 44%.
