Abstract — In This work, numerical study of two-dimensional steady flow analysis has been made on natural convection in a differentially heated vertical conical cylinder partially annular space. The heat transfer is assumed to take place by natural convection. Where the inner and outer surfaces of annulus are maintained at uniform wall temperature. The CFD FLUENT12.0 code is used to solve the governing equations of mass, momentum, energy quantities using constant properties and Boussinesq approximation for density variation. In addition, the numerical results of the heat transfer are discussed for various values of physical parameters of the fluid and geometric parameters of the annulus on the heat transfer. A good agreement of Nusselt number has been found between the present predictions and reference from the literature data.
