Effectiveness Analysis of Double Pipe Heat Exchanger with Curls Band in Various Angles
In the modern learning, effectiveness-NTU studies in a dual tube heat exchanger armed with curly band in view of numerous angles were experimentally deliberate. Additionally, discrepancy of the Dual effectiveness with heated water Reynolds numbers for dissimilar cold water flow rates were obtainable. These turbulators with unlike angles of 45 L, 60 L, 90 L, 120 L and 150 L were made of electrified plates with thickness of 1 mm and were attached in the internal tube of heat exchanger. The experimentations were conceded out at Reynolds numbers of 3000–13,400 at turbulent flow establishment. All over the research, hot and cold water rolled finished the internal pipe and the interplanetary between the pipes (annulus), correspondingly. It was strained to keep the bay hot and cold water temperatures at constant values. Effectiveness-NTU studies were made for the circumstances with and without curly bands including their different angles and associated to each other. Results displayed the substantial decision of turbulators on effectiveness (e) and number of heat transfer units (NTU) of dual tube heat exchanger. In totalling, some experiential associations uttering the domino effect were also industrialized constructed on curve fitting.
