CFD Analysis on Finned Tube Heat Exchanger using Alumina Nanofluid As Coolant
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 6
Abstract
Finned tube heat exchanger are used for heat transfer between air, gas and liquids or steam. Heat exchanger with finned heating surfaces, so-called finned tube heat exchanger, offer the possibility of heat transfer between gases and liquids significantly space-saving and is more efficient to implement than it is possible with straight tubes. finned tube heat exchangers are designed to transfer heat from clean air and gases with high efficiency on liquids or vapors, and vice versa. In this way the media can be heated, cooled or condensed, in a closely space. Finned tube heat exchangers can be used for different applications and in a variety of designs. In this work a model of finned tube heat exchanger was made and by using ANSYS fluent and used Al2O3 nanofluid as cooant for heat transfer enhancement and the analysis was carried out . CFD simulations are done for different concentration of Al2O3 at different flow speed . temperature contours in all the cases can be plotted by using CFD.by this we can clearly understand the heat transfer enhancement role of small concentration of nano particle on base fluid
