STUDI PENGARUH BEBAN PANAS TERHADAP KARAKTERISTIK PERPINDAHAN PANAS PADA HEAT EXCHANGER VERTICAL CHANNEL

Description:

Pengaruh dari perubahan beban panas terhadap karakteristik laju perpindahan panas konveksi bebas dari heat exchanger jajaran dua belas silinder dalam vertical channel dikaji dalam penelitian ini. Karakteristik gaya apung pada jajaran silinder ini dipengaruhi perubahan beban panas pada heat exchanger yang didapatkan dari perubahan laju alir massa oli panas. Uji eksperimental di laboratorium perpindahan panas dilakukan untuk mendapatkan laju perpindahan panas total heat exchanger. Uji eksperimental dilakukan pada gap ratio (b = S/d) 2.1 dan 4.2, dan pada laju alir massa oli panas bervariasi dari 0.0014 kg/s, 0.0028 kg/s, 0.0042 kg/s. Simulasi pola aliran udara yang melintasi jajaran silinder pada berbagai beban panas didapatkan dari studi numerik dengan menggunakan software CFD Fluent 6. Hasil eksperiment menunjukkan bahwa laju perpindahan panas total heat exchanger semakin tinggi dengan semakin besarnya beban panas untuk gap ratio yang sama. Simulasi pola aliran memperlihatkan profil wake pada downstream silinder semakin kecil dengan semakin besarnya beban panas. Hal ini dikarenakan semakin tingginya temperatur permukaan silinder pada beban panas yang semakin besar, mengakibatkan semakin besar pula gaya apung yang terjadi.
