Abstract :
Natural Convection is one of the major modes of heat transfer that can be classified in terms of being natural,
forced, gravitational, granular, or thermomagnetic. In the past decade, several studies on convection heat transfer in
many geometries, enhancement of heat transfer by adding nanofluids, effects of magnetic field in heat transfer, heat
transfer in a porous medium have been reported. The effects of heater length, as well as the Darcy (Da), Prandtl (Pr),
Reynolds (Re), Grashof (Gr) and Rayleigh numbers (Ra), the solid volume fraction of nanoparticles, the permeability
of the medium, and the inclination angle of geometry or heat source impacts on heat transfer are also investigated.
This paper reviews various researchers work on fluid flow and heat transfer behavior which is carried out by means
lattice Boltzmann method (LBM). LBM becomes an important tool in computational fluid dynamics area in recent
decades. The easy structure of programming, accuracy and less computational time gives LBM a big advantage. And
more over the flexibility of LBM allows to incorporate with conventional CFD tools to create a hybrid LBM is
greatly inspired by numerous scholars to work in this field. The principle extent of this paper to present a
comprehensive review on the exploration progress on natural convection using lattice Boltzmann method in recent
years.
