The Heat transfer is performed in three forms including conduction,
convection and radiation. Convection is one of the major modes which
classifies into three categories: natural, mixed or forced convection. In
recent years, much attention was given to the use of natural
convection with nanofluid in engineering application, satellite, cooling
system, solar collector etc. and many studies were conducted in this
area. This paper reviews some results of numerical, experimental and
theoretical studies in the field of natural convection heat transfer with
nanofluid and application of natural convection. Finally, some
suggestions are given for future studies in this area
