Abstract EN
Numerical simulations have been investigated to study the external free convective heat transfer from a vertically rectangular interrupted fin arrays.
The continuity, Naver-Stockes and energy equations have been solved for steady-state, incompressible, two dimensional, laminar with Boussiuesq approximation by Fluent 15 software.
The performance of interrupted fins was evaluated to gain the optimum ratio of interrupted length to fin length (yopt).
The different geometric parameters of project are assumed such as ratio of interrupted length to the fin length and the ratio of thickness to the fin length at different temperature.
Results show the employment of fin interruption technique for resetting the boundary layer, which was causing reduced in thermal resistance.
It was also concluded heat flux and heat transfer coefficient direct proportional with the temperature difference.
Another significant parameter is the value of y which has most advantageous at equal or less 25 after that there is not any significant on the value of Nu.
The enhancing of thermal performance of the fin and the reduction of the weight of it as a result of adding interruption to a vertical fin.
