Heat transfer by free convection plays important roles in various industrial and domestic fields. The study of heat transfer for cooling or heating purposes is the most important topic for engineering design, operation, analysis, and development. The heat transfer enhancement by utilizing different strategies promotes higher design quality which leads to energy saving, material, safety, and environment for different applications. The convective heat transfer rate (q) can be controlled by changing some of important parameters such as the type of working fluid, the system geometry, and thermal boundary conditions. The present paper represents a review on natural convection heat transfer enhancement in enclosures and cavities.
