Enhancement of Heat Transfer Performance of a Fin Tube Heat Exchanger Using Modified Delta Winglet Vortex Generator

The heat transfer performance of a fin tube heat exchanger is played very important role for getting maximum performance. For obtain the maximum heat transfer performance used a lot of active and passive techniques by the researchers. In this paper the heat transfer performanceenhanced by using the modified delta winglet vortex generator.The rectangular plate dimensions are considered 300mm*200mm*4mm, in which 12 Thermo couples are fitted for measuring the effect of temperature and pressure difference. The colburn factor is further determined in relation to the Reynolds number with the aid of mathematical computations. As is well known, the performance of heat transfer is directly correlated with the colburn factor. The experimental procedure repeats two times, first without a winglet and the second time it is performed with a winglet. A comparison of heat transfer performance is to be done with or without the winglet.
