CFD Analysis of Concentric Cylinder with and without Internal Fins

The purpose of this paper is to investigate in three-dimensional steady state natural convection fully developed heat transfer in a horizontal annuli in which the inner cylinder consisting working fluid hotter than the cylinder material. This simulation related to the mode of natural convection turbulence flow heat transfer in annuli for primitive variables pressure, velocities and temperature. The objective of this research is to further investigate numerically and the effect of internal fins on the heat transfer between concentric horizontal cylinders. Also studied about turbulence Rayleigh number how effect on annuli’s. Fins are employed to increase the heat transfer area, leading to an increase in the heat transfer between the cylinders so its use make consistent or not. Apart from there are many studies on convection mode due to subject of interest and engineering application on it.
