Abstract:
ABSTRACT The coiled wire inserts in microfin tubes are a typical technique that offers a higher heat transfer increase and, at the same time, only a mild pressure drop penalty. This study investigates the heat transfer characteristics and pressure drop in a microfin tube with and without coiled wire insert. Coiled wire insert has been used as one of the passive heat transfer enhancement techniques and are the most widely used tubes in several heat transfer applications. The experiments are conducted using two heat exchangers, contains microfin tube with coil wire inserts and microfin tube without coil wire insert.It contains the microfin tube in which Coiled wire insert is fabricated by bending iron wire into coil wire with coil diameter of ô€€€ 7.80 mm, coil pitch of 3.2 mm and length 610 mm. The tests are performed at the cold and hot water mass flow rates ranging between 0.01667 and 0.06667 kg/s. The inlet cold and hot water temperatures are between 20 0C and 250Cand between 40 0C to 45 0C, respectively. The experimental investigation and the calculations are discussed in this paper. Effect of different Reynolds numbers on the heat transfer rate, overall heat transfer rate, Heat transfer coefficient results, pressure drop and friction factor for microfin tube with and without coil wire insert are investigated.
