PENGARUH KONSENTRASI ETILEN GLIKOL TERHADAP EFEKTIVITAS PERPINDAHAN PANAS PADA ALAT DOUBLE PIPE HEAT EXCHANGER
نویسندگان
چکیده
Teknologi penukar panas sekarang ini telah diaplikasikan pada berbagai bidang teknologi. Salah satunya teknologi otomotif khususnya radiator. satu contoh untuk meningkatkan konduktivitas termal fluida adalah dengan merekayasa pendingan. Coolant cairan pendingin yang berbahan dasar etilen glikol digunakan mengurangi atau mengatur suhu suatu sistem. Pada penelitian dilakukan percobaan menggunakan alat Double Pipe Heat Exchanger mengetahui pengaruh laju alir dan konsentrasi terhadap efektivitas perpindahan metode Effectiveness. Variabel tetap dalam sebagai dingin air 75°C 25°C, jenis aliran Countercurrent. Sedangkan variabel bebasnya (etilen glikol) masuk: 100, 80, 60, 40, 20, 0 % yaitu 3, 6, 9, 12 liter/ menit. terikat keluar keluar. Untuk mendapatkan nilai perhitungan Qav, ΔTLMTD, U, NTU efektivitas. Dari diperoleh hasil berpengaruh panas, dimana semakin besar mengakibatkan meningkatnya Uav Konsentrasi juga mempengaruhi efektivitas, tinggi maka akan efektivitasnya, namun 80% 100% mengalami penurunan dikarenakan tersebut viskositas menjadi lebih sehingga menyebabkan turunnya Nilai terbaik 60 liter/menit sebesar 0,7072.

متن کاملHeat transfer enhancement due to air bubble injection into a horizontal double pipe heat exchanger
If an air flow is injected into a liquid fluid, many ambulant air bubbles are formed inside the fluid. Air bubbles move inside the liquid fluid because of the buoyancy force, and the mobility of these air bubbles makes sizable commixture and turbulence inside the fluid. This mechanism was employed to enhance the heat transfer rate of a horizontal double pipe heat exchanger in this paper. Howeve...
متن کاملAn experimental investigation of heat transfer of Fe2O3/Water nanofluid in a double pipe heat exchanger
One way to increase the heat transfer is to use perforated twisted tapes with different hole diameters, which largely improve heat transfer with an increase in the heat transfer area at the constant volume and more mixed flow. In the previous studies, the effect of nanofluids with perforated twisted tapes is less studied. In this work, the performance of water / iron oxide nanofluid in a double...
