Review on Heat Transfer Enhancement Through Fins Using Surface Modifications
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 3
Abstract
Extended surfaces are employed in many engineering applications such as heat exchanger, chemical reactor and micro-electronic devices; hence many techniques have been investigated on enhancement of heat transfer rate. Bergles classified heat transfer intensification methods in to three categories- Active techniques, Passive techniques and combination of these two. But it has been reported that in many cases heat transfer enhancement through passive methods are used as this technique do not require any external power source for this purpose.Passive method generally uses surface or geometrical modifications to the flow channel by incorporating inserts, artificial roughness or material removal from the surface. Passive methods when adopted particularly in Heat exchanger applications proved that the overall thermal performance improved significantly. This paper presents the review on heat transfer enhancement using passive methods and explores how extended surfaces with geometrical modifications like dimples, protrusions, grooves etc., improves heat transfer characteristics.This information is useful for future use of the geometrical modifications of extended surfaces based on the space availability and cost.
