This paper presents a review of investigation of thermal performance in natural convection from different geometrical fins. There are many methods for investigation of thermal performance of fins with different geometrical parameters. The thermal performance in natural convection from different geometrical fins being reviewed includes analysing the natural convective heat transfer from vertical fins, also similarity solutions for boundary layer equations for the cases of uniform surface heat flux, analytical work on vertical channels, an analytical study to investigate the natural convective heat transfer from two parallel plates, correlated the Nusselt number based on the squared root of the wetted area for the three dimensional bodies, a numerical approach to investigate the developing flow in the channel and the heat transfer between symmetrically heated, isothermal plates, the heat transfer from inclined interrupted fin channels, calculated natural heat transfer coefficients for four different fin arrays and three different base plates, the natural convection and radiation heat transfer From twelve large vertically based fin arrays also naturally cooled vertical shrouded fins. This present paper can be used as the first guideline for the researcher for changing different orientation of the interrupted fins for 3-D analysis by using FLUENT software also numerical model for investigation of interruption effects
