Thermal-hydraulic performance analysis cold side of the plate heat exchanger using water-water
Journal Title: Бюллетень науки и практики - Year 2018, Vol 4, Issue 5
Abstract
In this research, the thermal–hydraulic performance of plate heat exchanger (Ridan HHN no. 04) used in domestic water system is investigated experimentally. The hot water inlet keeps temperature and flow rate constant at 70 °C and 0.1 l/s, the cold–water inlet remained 11 °C with different velocity. The heat transfer coefficient can reach maximum when velocity of cold water is 0.2 m/s. Then the convective heat transfer coefficient increases with enhancement of Reynolds number and it is stable after more than 1200. Moreover, it is observed that Fanning friction factor decreases with an increase of the Reynolds number and it is showed by the empirical correlation. Therefore, it is possible to find that the increase of the Peclet number results in an increase of the Nusselt number as well when Peclet number small than 200. Finally, we get reference idea how to be cooling in the particular case using plate heat exchanger.
