Thermal energy storage system with phase change materials has attracted a great attention because of its important role in latent heat energy conservation. TESS gives a high thermal storage density with a wide range of temperature. This paper considers the analytical solution of outward melting/solidification of phase change materials in thermal energy storage system. Due to its non-linear behaviour, it is complicated to have exact solution of melting process and predict the behavior of interface movement, heat transfer rate. Heat balance integral method is applied to solve one dimensional outward melting problem in cylindrical geometry. Interface location, heat transfer rate and heat transfer with time is obtained for the geometry. Matlab code has been written to obtained the results.
