Abstract
Effect of non-uniform heat transfer coefficient on melting of solid phase filled in horizontal circular cylinders has been studied by numerical analysis. Conduction and convection analyses were performed under the condition of uniform and non-uniform heat transfer coefficient. The numerical results were compared with the experimental results. For small Rayleigh number in the liquid phase, melting process is dominated by thermal convection. With increase in Rayleigh number, natural convection dominates the heat transfer and the effect of non-uniform heat transfer coefficient on melting process is reduced..
