Karakteristik perpindahan panas pada grooved double pipe heat exchanger  diteliti secara experimental. Penelitian ini bertujuan untuk mengungkap fenomena karakteristik temperatur fluida dingin pada proses perpindahan panas pada heat exchanger . Dalam penelitian ini, digunakan air sebagai fluida panas dan dingin dengan pola aliran counter flow dan laju aliran sama untuk kedua fluida yaitu 15 lpm. Groove diposisikan pada daerah annulus yaitu pada dinding luar tube dengan bentuk rectangular dan pola circumferential.  Karakteristik dimensi groove yaitu dalam tinggi groove adalah 0,3 mm; jarak antar groove adalah 8 mm; dan lebar groove sebagai variabel bebas yaitu 1 mm dan 2 mm. Temperatur fluida panas yang digunakan adalah 50 ± 0,50C sedangkan temperatur fluida dingin adalah 30 ± 0,50C. Data hasil pengukuran temperatur pada sisi masuk dan keluar penukar kalor dengan lebar groove 1 mm dan 2 mm dibandingkan untuk mengetahui karakteristik peningkatan temperatur fluida dingin. Pada penelitian ini digunakan metode laju temperatur dan akselerasi temperatur untuk membandingkan variabel dalam penelitian ini. Hasil penelitian ini mengungkap bahwa pemasangan groove meningkatkan jumlah kalor yang mampu diserap fluida dingin. Heat exchanger  dengan lebar groove 1 mm, mampu menyerap panas ±2,3 % lebih baik dibandingkan dengan heat exchanger dengan lebar groove 2 mm.

A double pipe heat exchanger is significant device for many industrial applications. In this paper, an experimental study using both porous media and nanofluid to enhance heat transfer in a double pipe heat exchanger is performed. The test rig has been fabricated with inner copper pipe of 1.10 m length, 16 mm, and 14 mm outside and inside diameter, respectively. While, the outer PVC pipe is 1 m length, 31 mm, and 27 mm outside and inside diameter, respectively. The inner pipe has been filling with 3 mm diameters of steel balls porous media. The experimental tests were performed utilizing alumina nanofluid (Al2O3-water) with two volume concentrations 0.5% and 1%. The volume flow-rates are in the range of (2-5) Lpm and 10 Lpm through inner and outer pipe, respectively. It was conducted with a constant 28?C inlet temperature of cold fluid-flow inside the inner pipe and 50?C inlet temperature of hot fluid-flow inside the outer pipe. Results indicated that the heat transfer enhanced as nanofluid volume concentrations and volume flow-rates increase. It was observed that effectiveness increases as increase of flow-rate and nanofluid concentrations.
