Abstract

A numerical study was done to analyze the conjugate convective thermal transmission through an enclosure containing a solid object. The geometrical shape of the inserted object was changed many times to check the influence of changing the geometry on both heat transfer process and fluid flow. COMSOL Multiphysics 6.0 was utilized to present the findings in terms of isotherms , stream function and Nusslet number. The working fluid here is air of prandtle number of 0.7. The effect of Ra on both Nu and the heat transfer process was studied here. There is also a comparison between the results of the different geometries to check which one has achieved the best results. It is worthy to mention that a validation process was done with a previous study to check the validity of the past results. The application of this field is so common in nuclear reactors and energy storage.
