“…The double fin and tube heat exchanger is generally designed for a wide range of applications such as marine exhaust gas boilers for waste heat recovery from coal-fired boilers (Singh et al, 2016a(Singh et al, ,b, 2017 due to good anti-wear and anti-fouling performance, compact design, stability (Chen and Lai, 2012;Jin et al, 2013Jin et al, , 2016. To investigate the effectiveness of VGs, rectangular winglet vortex generator (RWVG) are selected considering their heat transfer enhancement performance better than delta winglets (Li et al, 2015).…”

Vortex generator is considered as an effective device for augmentation of the thermal-hydraulic performance of a heat exchanger. The aim of present study is to examine the influence of vortex generators on a double fin and tube heat exchanger performance. Vortex generator of rectangular winglet type is chosen and investigated at different angles of attack 0 • , −10 • and −20 • with the flow direction. Three-dimensional numerical model is developed and simulations are performed for a Reynolds number range 5000 ≤ Re ≤ 11000 taking conjugate heat transfer into account. The heat transfer and pressure loss characteristics are determined and analyzed for an in-line configuration of a fin and tube heat exchanger. In order to evaluate the enhancement in the performance on an equitable basis, the heat exchanger with plain fin surface is considered as a reference design. Results show that the angle of attack of a vortex generator has a significant impact on the volume goodness factor, and enhance the thermal performance of a fin and tube heat exchanger in comparison to the design with plain fin. The vortex generator at an angle of attack −10 • is found to perform superior over the Reynolds number range studied. At Re = 5000, the vortex generator with an angle of attack −10 • increases the volume goodness factor by 32% with respect to the baseline heat exchanger design.

Abstract-The heat exchanger element H-type finned tube has a high enhancement of heat transfer and excellent self-cleaning property and has evident effect in the boiler renovation, especially in the field of flue gas waste heat recovery. In this paper, the heat transfer and resistance characteristics of Htype finned tube are studied by the experimental system of open high-temperature wind tunnel. The effects of fin width, fin height, fin pitch and air velocity on fin efficiency, convective heat transfer coefficient and pressure drop are examined. It is found that as air velocity, fin height and fin width increase, fin efficiency decreases. Convective heat transfer coefficient is proportional to fin pitch but inversely proportional to fin height and fin width. Pressure drop increases with the increase of fin height and fin width. Then the correlations of fin efficiency, Nu and Eu are fitted.

H-type finned tube heat exchanger elements maintain a high capacity for heat transfer, possess superior self-cleaning properties and retain the ability to effect flue gas waste heat recovery in boiler renovations. In this paper, the heat transfer and pressure drop characteristics of H-type finned tube banks are studied via an experimental open high-temperature wind tunnel system. The effects of fin width, fin height, fin pitch and air velocity on fin efficiency, convective heat transfer coefficient, integrated heat transfer capacity and pressure drop are examined. The results indicate that as air velocity, fin height and fin width increase, fin efficiency decreases. Convective heat transfer coefficient is proportional to fin pitch, but inversely proportional to fin height and fin width. Integrated heat transfer capacity is related to fin efficiency, convective heat transfer coefficient and finned ratio. Pressure drop increases with the increase of fin height and fin width. Finally, predictive correlations of fin efficiency, Nusselt number and Euler Number are developed based on the experimental data.
