Abstract |
|
Present research paper suggests geometrical modification methods to improve heat transfer rate of automobile air cooled engine fins by disruption of thermal boundary layer. Thermal boundary layer plays vital role in heat transfer from fins and act as barrier in convective heat transfer. So many methods and designs of geometry available to break thermal boundary layer, use of vortex generator, perforation on fin surface, and use of wavy fins are some of examples. Numerical simulation work has been carried out on combination of louvered shape and vortex generator geometries, combination of both geometries here are used on engine fin in order to enhance heat transfer by phenomenon of thermal boundary layer disruption. |
