In this work, natural convection heat transfer and fluid flow is reviewed in different types ofenclosures with localized heating, considering the working fluid as a simple fluid or a nanofluid.Experimental findings are considered in addition to two and three dimensional numerical studies.The common objective of the reviewed work is to investigate the effects of type and location oflocal heat sources as well as the effects of the different configurations of cavities and boundaryconditions on the enclosed fluid flow and heat transfer. Important correlations, concluded fromthese studies, are summarized.
