Abstract

In this study, the effect of different conditions for making gap in the triangular fin has been investigated on the free convective heat transfer coefficient. Making gap in suitable places on the monolith triangular fins can increase the free convective heat transfer coefficient, so the purpose of this study is to reach the optimum condition of configuration for gaps by which the free convective heat transfer coefficient is increased. For this purpose, eight different conditions of vertical triangular fins located on a vertical plate were made and investigated. One of these conditions doesn't have gap and the other seven conditions had different kinds of gaps configuration. The obtained results showed that the optimum condition is a condition with the configuration of three gaps on the length of the triangular fin. Also for validation of experimental results, the numerical modeling of all the above mentioned conditions was done by using the fluent software.
